Title
netfilter: nf_tables: reject mismatching sum of field_len with set key length
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: reject mismatching sum of field_len with set key length
The field length description provides the length of each separated key
field in the concatenation, each field gets rounded up to 32-bits to
calculate the pipapo rule width from pipapo_init(). The set key length
provides the total size of the key aligned to 32-bits.
Register-based arithmetics still allows for combining mismatching set
key length and field length description, eg. set key length 10 and field
description [ 5, 4 ] leading to pipapo width of 12.

Per kernel scoring guidance, netfilter/nftables netlink paths are Local.\nAC:L - Triggering is fully deterministic and entirely attacker-controlled: create an interval+concat set with any key length not a multiple of 4 (e.g. klen=10 with field description [5,4]) and add one ranged element. No race, no memory-layout luck, and pipapo is the only backend that accepts multi-field interval sets so the vulnerable code is always selected.\nPR:L - nfnetlink_rcv_msg() checks netlink_net_capable(skb, CAP_NET_ADMIN), which is satisfied against the network namespace\u0027s owning user namespace, so any unprivileged local user can obtain it with `unshare -Urn` and then create the malformed set. This is the standard unprivileged-user-namespace path used by public nftables exploits.\nUI:N - The attacker performs all steps themselves through netlink; no victim action, mount, or file open is needed.\nS:U - The out-of-bounds accesses and the corrupted pipapo state remain within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - pipapo consumes round_up(klen,4) bytes from buffers holding only klen, reading past the end of the heap-allocated element extension (key_end) and consuming uninitialized kernel stack bytes from the on-stack struct nft_set_elem. Those out-of-bounds values are baked into the set\u0027s lookup tables and can be recovered by an attacker probing match results through the packet path, yielding kernel heap/stack disclosure.\nI:H - Kernel data structures (the pipapo lookup and mapping tables) are populated from memory outside the intended key object, so set state is corrupted with out-of-bounds content and packet-matching verdicts, maps, and NAT decisions become dependent on that data. Consistent with kernel-CNA precedent for local nftables/ebtables out-of-bounds accesses, the memory-safety violation is treated as High integrity impact.\nA:H - The slab out-of-bounds read past the element extension is a KASAN-reportable memory-safety violation that panics on hardened/panic_on_warn configurations and can fault when the object abuts an unmapped region, and the corrupted range endpoints drive pipapo_expand() rule expansion from garbage. Any such kernel crash is scored High."

Title
net: let net.core.dev_weight always be non-zero
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: let net.core.dev_weight always be non-zero
The following problem was encountered during stability test:
(NULL net_device): NAPI poll function process_backlog+0x0/0x530 \
returned 1, exceeding its budget of 0.
------------[ cut here ]------------
list_add double add: new=ffff88905f746f48, prev=ffff88905f746f48, \

The reproduction command is as follows:
sysctl -w net.core.dev_weight=0
ping 127.0.0.1
This is because when the napi's weight is set to 0, process_backlog() may
return 0 and clear the NAPI_STATE_SCHED bit of napi->state, causing this
napi to be re-polled in net_rx_action() until __do_softirq() times out.
Since the NAPI_STATE_SCHED bit has been cleared, napi_schedule_rps() can
be retriggered in enqueue_to_backlog(), causing this issue.
Making the napi's weight always non-zero solves this problem.
Triggering this issue requires system-wide admin (setting is
not namespaced).
Severity
No CVSS data available.

Title
USB: hub: Ignore non-compliant devices with too many configs or interfaces
Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: hub: Ignore non-compliant devices with too many configs or interfaces
Robert Morris created a test program which can cause
usb_hub_to_struct_hub() to dereference a NULL or inappropriate
pointer:
Oops: general protection fault, probably for non-canonical address
0xcccccccccccccccc: 0000 [#1] SMP DEBUG_PAGEALLOC PTI
CPU: 7 UID: 0 PID: 117 Comm: kworker/7:1 Not tainted 6.13.0-rc3-00017-gf44d154d6e3d #14
Hardware name: FreeBSD BHYVE/BHYVE, BIOS 14.0 10/17/2021
Workqueue: usb_hub_wq hub_event
RIP: 0010:usb_hub_adjust_deviceremovable+0x78/0x110
...

The cause of this error is that the device has two interfaces, and the
hub driver binds to interface 1 instead of interface 0, which is where
usb_hub_to_struct_hub() looks.
We can prevent the problem from occurring by refusing to accept hub
devices that violate the USB spec by having more than one
configuration or interface.

The vulnerable code is bound to the network stack and reachable from remotely originated packets, so Network is the correct and higher-severity classification.\nAC:H - The attacker fully controls and can sustain the ARP-transmit side of the race, but the other side \u2014 a `struct net` being freed via `cleanup_net()` or a device migrating namespaces \u2014 is background system activity the network attacker cannot command. Because that condition lies outside attacker control, complexity is High.\nPR:N - There is no capability check, credential check, or authentication gate anywhere on the path from packet receipt/neighbour resolution to `arp_xmit()`; ARP solicitation and reply generation happen unconditionally in softirq context. An entirely unauthenticated attacker reaches the vulnerable code.\nUI:N - The attacker\u0027s own packets cause the kernel to emit ARP and execute the vulnerable code; no victim must mount a filesystem, open a file, or take any other action.\nS:U - The use-after-free of `struct net` and the resulting corruption stay entirely within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - A use-after-free of `struct net` lets `nf_hook()` read `net-\u003enf.hooks_arp[]` and every ARP-family hook read `state-\u003enet` out of freed, potentially reallocated slab memory. Per kernel guidance a UAF gives the attacker control over the freed object\u0027s contents and thus an arbitrary kernel-memory read primitive.\nI:H - The stale `net` yields a `hook_head` pointer from freed memory, and `nf_hook_slow()` then performs an indirect call through `e-\u003ehooks[s].hook` \u2014 a direct function-pointer hijack primitive if the netns slab is reallocated with sprayed data. Hooks also write through `state-\u003enet`, corrupting reused kernel objects.\nA:H - Dereferencing a freed `struct net` and calling through a garbage `nf_hook_entries` reliably oopses or panics the kernel, and is a KASAN-reportable memory-safety violation that panics on hardened configurations. Any such kernel crash is scored High."

The above transcript shows that ACPI pointed a 16 MiB buffer for the log
events because RSI maps to the 'order' parameter of __alloc_pages_noprof().
Address the bug by moving from devm_kmalloc() to devm_add_action() and
kvmalloc() and devm_add_action().

Title
usb: xhci: Fix NULL pointer dereference on certain command aborts
Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: xhci: Fix NULL pointer dereference on certain command aborts
If a command is queued to the final usable TRB of a ring segment, the
enqueue pointer is advanced to the subsequent link TRB and no further.
If the command is later aborted, when the abort completion is handled
the dequeue pointer is advanced to the first TRB of the next segment.
If no further commands are queued, xhci_handle_stopped_cmd_ring() sees
the ring pointers unequal and assumes that there is a pending command,
so it calls xhci_mod_cmd_timer() which crashes if cur_cmd was NULL.
Don't attempt timer setup if cur_cmd is NULL. The subsequent doorbell
ring likely is unnecessary too, but it's harmless. Leave it alone.
This is probably Bug 219532, but no confirmation has been received.
The issue has been independently reproduced and confirmed fixed using
a USB MCU programmed to NAK the Status stage of SET_ADDRESS forever.
Everything continued working normally after several prevented crashes.

Title
gtp: Destroy device along with udp socket's netns dismantle.
Summary
In the Linux kernel, the following vulnerability has been resolved:
gtp: Destroy device along with udp socket's netns dismantle.
gtp_newlink() links the device to a list in dev_net(dev) instead of
src_net, where a udp tunnel socket is created.
Even when src_net is removed, the device stays alive on dev_net(dev).
Then, removing src_net triggers the splat below. [0]
In this example, gtp0 is created in ns2, and the udp socket is created
in ns1.
ip netns add ns1
ip netns add ns2
ip -n ns1 link add netns ns2 name gtp0 type gtp role sgsn
ip netns del ns1
Let's link the device to the socket's netns instead.
Now, gtp_net_exit_batch_rtnl() needs another netdev iteration to remove
all gtp devices in the netns.
[0]:

Title
exfat: fix the infinite loop in exfat_readdir()
Summary
In the Linux kernel, the following vulnerability has been resolved:
exfat: fix the infinite loop in exfat_readdir()
If the file system is corrupted so that a cluster is linked to
itself in the cluster chain, and there is an unused directory
entry in the cluster, 'dentry' will not be incremented, causing
condition 'dentry < max_dentries' unable to prevent an infinite
loop.
This infinite loop causes s_lock not to be released, and other
tasks will hang, such as exfat_sync_fs().
This commit stops traversing the cluster chain when there is unused
directory entry in the cluster to avoid this infinite loop.
Severity
No CVSS data available.

net_sched: cls_flow: validate TCA_FLOW_RSHIFT attribute
Summary
In the Linux kernel, the following vulnerability has been resolved:
net_sched: cls_flow: validate TCA_FLOW_RSHIFT attribute
syzbot found that TCA_FLOW_RSHIFT attribute was not validated.
Right shitfing a 32bit integer is undefined for large shift values.
UBSAN: shift-out-of-bounds in net/sched/cls_flow.c:329:23
shift exponent 9445 is too large for 32-bit type 'u32' (aka 'unsigned int')
CPU: 1 UID: 0 PID: 54 Comm: kworker/u8:3 Not tainted 6.13.0-rc3-syzkaller-00180-g4f619d518db9 #0

Title
sched: sch_cake: add bounds checks to host bulk flow fairness counts
Summary
In the Linux kernel, the following vulnerability has been resolved:
sched: sch_cake: add bounds checks to host bulk flow fairness counts
Even though we fixed a logic error in the commit cited below, syzbot
still managed to trigger an underflow of the per-host bulk flow
counters, leading to an out of bounds memory access.
To avoid any such logic errors causing out of bounds memory accesses,
this commit factors out all accesses to the per-host bulk flow counters
to a series of helpers that perform bounds-checking before any
increments and decrements. This also has the benefit of improving
readability by moving the conditional checks for the flow mode into
these helpers, instead of having them spread out throughout the
code (which was the cause of the original logic error).
As part of this change, the flow quantum calculation is consolidated
into a helper function, which means that the dithering applied to the
ost load scaling is now applied both in the DRR rotation and when a
sparse flow's quantum is first initiated. The only user-visible effect
of this is that the maximum packet size that can be sent while a flow
stays sparse will now vary with +/- one byte in some cases. This should
not make a noticeable difference in practice, and thus it's not worth
complicating the code to preserve the old behaviour.

Although cake also processes remotely-originated traffic on routers, the reliable and primary attack path is local, consistent with tc/qdisc classification.\nAC:L - The vulnerable host-fairness accounting is active in cake\u0027s default `triple-isolate` flow mode, and the attacker fully controls the packet 5-tuples used for the set-associative hash, so filling an 8-way set and forcing the mis-targeted decrement is deterministic and repeatable.\nPR:L - Qdisc installation is gated by `netlink_net_capable(skb, CAP_NET_ADMIN)`, which is evaluated against the netns user namespace, so any unprivileged user can obtain it with `unshare -Urn` and then attach cake to a loopback/veth device.\nUI:N - The attacker performs the qdisc setup and generates the triggering traffic entirely on their own; no action by any other user or administrator is needed.\nS:U - The out-of-bounds read and the counter corruption are confined to kernel memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The u16 underflow makes `quantum_div[host_load]` read up to ~128 KB beyond a 1025-entry static array, and the value is folded into `flow-\u003edeficit`, which is exported via `TCA_CAKE_STATS_DEFICIT` \u2014 repeated samples defeat the random dithering and recover out-of-bounds kernel data, with the index steerable by additional spurious decrements.\nI:L - The bug persistently corrupts the per-host bulk-flow counters and injects out-of-bounds data into the scheduler\u0027s deficit state, modifying kernel data the attacker should not be able to touch, but there is no out-of-bounds write and no control over the written values.\nA:H - The wild index trips `WARN_ON(host_load \u003e CAKE_QUEUES)` (a panic under `panic_on_warn`) and reads far past the module\u0027s `.bss` into potentially unmapped vmalloc space, causing an oops; the qdisc state stays corrupted so the condition recurs on every dequeue."

---[ end trace 0000000000000000 ]---
Its possible that two threads call tcp_v6_do_rcv()/sk_forward_alloc_add()
concurrently when sk->sk_state == TCP_LISTEN with sk->sk_lock unlocked,
which triggers a data-race around sk->sk_forward_alloc:
tcp_v6_rcv
tcp_v6_do_rcv
skb_clone_and_charge_r
sk_rmem_schedule
__sk_mem_schedule
sk_forward_alloc_add()
skb_set_owner_r
sk_mem_charge
sk_forward_alloc_add()
__kfree_skb
skb_release_all
skb_release_head_state
sock_rfree
sk_mem_uncharge
sk_forward_alloc_add()
sk_mem_reclaim
// set local var reclaimable
__sk_mem_reclaim
sk_forward_alloc_add()
In this syzkaller testcase, two threads call
tcp_v6_do_rcv() with skb->truesize=768, the sk_forward_alloc changes like
this:
(cpu 1) | (cpu 2) | sk_forward_alloc
... | ... | 0
__sk_mem_schedule() | | +4096 = 4096
| __sk_mem_schedule() | +4096 = 8192
sk_mem_charge() | | -768 = 7424
| sk_mem_charge() | -768 = 6656
... | ... |
sk_mem_uncharge() | | +768 = 7424
reclaimable=7424 | |
| sk_mem_uncharge() | +768 = 8192
| reclaimable=8192 |
__sk_mem_reclaim() | | -4096 = 4096
| __sk_mem_reclaim() | -8192 = -4096 != 0
The skb_clone_and_charge_r() should not be called in tcp_v6_do_rcv() when
sk->sk_state is TCP_LISTEN, it happens later in tcp_v6_syn_recv_sock().
Fix the same issue in dccp_v6_do_rcv().

No memory layout, timing window outside attacker influence, or victim state is required, and syzkaller reproduces it routinely.\nPR:N - The racing code runs while processing a SYN on a listening socket, entirely before connection establishment or any authentication, so no credentials of any kind are needed. Setting the `IPV6_RECV*` option that arms the path is done by the victim server (or by an unprivileged local user on their own listener), not by the attacker.\nUI:N - Triggering requires only that packets be sent to an already-listening socket; no action by any local user or administrator is needed.\nS:U - The corrupted state (`sk-\u003esk_forward_alloc`, `tcp_memory_allocated`, memcg skmem counters) and the resulting warning/panic are all within the kernel\u0027s own security authority, with no crossing into a hypervisor, IOMMU, or other separate authority.\nC:N - The defect is a non-atomic read-modify-write on integer accounting counters; it produces no out-of-bounds read, no use-after-free, and no path by which memory contents or kernel pointers are disclosed to the attacker.\nI:N - No attacker-controlled data is written and no memory corruption primitive is created \u2014 only the socket\u0027s own memory-accounting counters become inconsistent, which is not a modification of protected data or control flow.\nA:H - The imbalance trips `WARN_ON_ONCE(sk_forward_alloc_get(sk))` in `inet_sock_destruct()` from softirq context, which is an immediate kernel panic on `panic_on_warn` systems, and the over-reclaim corrupts the global `tcp_memory_allocated` counter and memcg skmem accounting, breaking system-wide TCP memory limits (unbounded growth toward OOM, or permanent memory pressure across all TCP sockets). It is repeatable at will by an unauthenticated remote attacker."

Title
Squashfs: check the inode number is not the invalid value of zero
Summary
In the Linux kernel, the following vulnerability has been resolved:
Squashfs: check the inode number is not the invalid value of zero
Syskiller has produced an out of bounds access in fill_meta_index().
That out of bounds access is ultimately caused because the inode
has an inode number with the invalid value of zero, which was not checked.
The reason this causes the out of bounds access is due to following
sequence of events:
1. Fill_meta_index() is called to allocate (via empty_meta_index())
and fill a metadata index. It however suffers a data read error
and aborts, invalidating the newly returned empty metadata index.
It does this by setting the inode number of the index to zero,
which means unused (zero is not a valid inode number).
2. When fill_meta_index() is subsequently called again on another
read operation, locate_meta_index() returns the previous index
because it matches the inode number of 0. Because this index
has been returned it is expected to have been filled, and because
it hasn't been, an out of bounds access is performed.
This patch adds a sanity check which checks that the inode number
is not zero when the inode is created and returns -EINVAL if it is.

Title
netfilter: nf_tables: reject mismatching sum of field_len with set key length
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: reject mismatching sum of field_len with set key length
The field length description provides the length of each separated key
field in the concatenation, each field gets rounded up to 32-bits to
calculate the pipapo rule width from pipapo_init(). The set key length
provides the total size of the key aligned to 32-bits.
Register-based arithmetics still allows for combining mismatching set
key length and field length description, eg. set key length 10 and field
description [ 5, 4 ] leading to pipapo width of 12.

"value": "AV:L - The vulnerability is reached exclusively through nfnetlink/netlink configuration messages to the nf_tables subsystem (NFT_MSG_NEWSET / NFT_MSG_NEWSETELEM), which require local system access. Per kernel scoring guidance, netfilter/nftables netlink paths are Local.\nAC:L - Triggering is fully deterministic and entirely attacker-controlled: create an interval+concat set with any key length not a multiple of 4 (e.g. klen=10 with field description [5,4]) and add one ranged element. No race, no memory-layout luck, and pipapo is the only backend that accepts multi-field interval sets so the vulnerable code is always selected.\nPR:L - nfnetlink_rcv_msg() checks netlink_net_capable(skb, CAP_NET_ADMIN), which is satisfied against the network namespace\u0027s owning user namespace, so any unprivileged local user can obtain it with `unshare -Urn` and then create the malformed set. This is the standard unprivileged-user-namespace path used by public nftables exploits.\nUI:N - The attacker performs all steps themselves through netlink; no victim action, mount, or file open is needed.\nS:U - The out-of-bounds accesses and the corrupted pipapo state remain within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - pipapo consumes round_up(klen,4) bytes from buffers holding only klen, reading past the end of the heap-allocated element extension (key_end) and consuming uninitialized kernel stack bytes from the on-stack struct nft_set_elem. Those out-of-bounds values are baked into the set\u0027s lookup tables and can be recovered by an attacker probing match results through the packet path, yielding kernel heap/stack disclosure.\nI:H - Kernel data structures (the pipapo lookup and mapping tables) are populated from memory outside the intended key object, so set state is corrupted with out-of-bounds content and packet-matching verdicts, maps, and NAT decisions become dependent on that data. Consistent with kernel-CNA precedent for local nftables/ebtables out-of-bounds accesses, the memory-safety violation is treated as High integrity impact.\nA:H - The slab out-of-bounds read past the element extension is a KASAN-reportable memory-safety violation that panics on hardened/panic_on_warn configurations and can fault when the object abuts an unmapped region, and the corrupted range endpoints drive pipapo_expand() rule expansion from garbage. Any such kernel crash is scored High."

Title
net: let net.core.dev_weight always be non-zero
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: let net.core.dev_weight always be non-zero
The following problem was encountered during stability test:
(NULL net_device): NAPI poll function process_backlog+0x0/0x530 \
returned 1, exceeding its budget of 0.
------------[ cut here ]------------
list_add double add: new=ffff88905f746f48, prev=ffff88905f746f48, \
next=ffff88905f746e40.

entry_SYSCALL_64_after_hwframe+0x76/0x7e
The reproduction command is as follows:
sysctl -w net.core.dev_weight=0
ping 127.0.0.1
This is because when the napi's weight is set to 0, process_backlog() may
return 0 and clear the NAPI_STATE_SCHED bit of napi->state, causing this
napi to be re-polled in net_rx_action() until __do_softirq() times out.
Since the NAPI_STATE_SCHED bit has been cleared, napi_schedule_rps() can
be retriggered in enqueue_to_backlog(), causing this issue.
Making the napi's weight always non-zero solves this problem.
Triggering this issue requires system-wide admin (setting is
not namespaced).
Severity
No CVSS data available.

Title
USB: hub: Ignore non-compliant devices with too many configs or interfaces
Summary
In the Linux kernel, the following vulnerability has been resolved:
USB: hub: Ignore non-compliant devices with too many configs or interfaces
Robert Morris created a test program which can cause
usb_hub_to_struct_hub() to dereference a NULL or inappropriate
pointer:
Oops: general protection fault, probably for non-canonical address
0xcccccccccccccccc: 0000 [#1] SMP DEBUG_PAGEALLOC PTI
CPU: 7 UID: 0 PID: 117 Comm: kworker/7:1 Not tainted 6.13.0-rc3-00017-gf44d154d6e3d #14
Hardware name: FreeBSD BHYVE/BHYVE, BIOS 14.0 10/17/2021
Workqueue: usb_hub_wq hub_event
RIP: 0010:usb_hub_adjust_deviceremovable+0x78/0x110
...

The cause of this error is that the device has two interfaces, and the
hub driver binds to interface 1 instead of interface 0, which is where
usb_hub_to_struct_hub() looks.
We can prevent the problem from occurring by refusing to accept hub
devices that violate the USB spec by having more than one
configuration or interface.

The vulnerable code is bound to the network stack and reachable from remotely originated packets, so Network is the correct and higher-severity classification.\nAC:H - The attacker fully controls and can sustain the ARP-transmit side of the race, but the other side \u2014 a `struct net` being freed via `cleanup_net()` or a device migrating namespaces \u2014 is background system activity the network attacker cannot command. Because that condition lies outside attacker control, complexity is High.\nPR:N - There is no capability check, credential check, or authentication gate anywhere on the path from packet receipt/neighbour resolution to `arp_xmit()`; ARP solicitation and reply generation happen unconditionally in softirq context. An entirely unauthenticated attacker reaches the vulnerable code.\nUI:N - The attacker\u0027s own packets cause the kernel to emit ARP and execute the vulnerable code; no victim must mount a filesystem, open a file, or take any other action.\nS:U - The use-after-free of `struct net` and the resulting corruption stay entirely within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - A use-after-free of `struct net` lets `nf_hook()` read `net-\u003enf.hooks_arp[]` and every ARP-family hook read `state-\u003enet` out of freed, potentially reallocated slab memory. Per kernel guidance a UAF gives the attacker control over the freed object\u0027s contents and thus an arbitrary kernel-memory read primitive.\nI:H - The stale `net` yields a `hook_head` pointer from freed memory, and `nf_hook_slow()` then performs an indirect call through `e-\u003ehooks[s].hook` \u2014 a direct function-pointer hijack primitive if the netns slab is reallocated with sprayed data. Hooks also write through `state-\u003enet`, corrupting reused kernel objects.\nA:H - Dereferencing a freed `struct net` and calling through a garbage `nf_hook_entries` reliably oopses or panics the kernel, and is a KASAN-reportable memory-safety violation that panics on hardened configurations. Any such kernel crash is scored High."

The above transcript shows that ACPI pointed a 16 MiB buffer for the log
events because RSI maps to the 'order' parameter of __alloc_pages_noprof().
Address the bug by moving from devm_kmalloc() to devm_add_action() and
kvmalloc() and devm_add_action().

Title
usb: xhci: Fix NULL pointer dereference on certain command aborts
Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: xhci: Fix NULL pointer dereference on certain command aborts
If a command is queued to the final usable TRB of a ring segment, the
enqueue pointer is advanced to the subsequent link TRB and no further.
If the command is later aborted, when the abort completion is handled
the dequeue pointer is advanced to the first TRB of the next segment.
If no further commands are queued, xhci_handle_stopped_cmd_ring() sees
the ring pointers unequal and assumes that there is a pending command,
so it calls xhci_mod_cmd_timer() which crashes if cur_cmd was NULL.
Don't attempt timer setup if cur_cmd is NULL. The subsequent doorbell
ring likely is unnecessary too, but it's harmless. Leave it alone.
This is probably Bug 219532, but no confirmation has been received.
The issue has been independently reproduced and confirmed fixed using
a USB MCU programmed to NAK the Status stage of SET_ADDRESS forever.
Everything continued working normally after several prevented crashes.

Title
gtp: Destroy device along with udp socket's netns dismantle.
Summary
In the Linux kernel, the following vulnerability has been resolved:
gtp: Destroy device along with udp socket's netns dismantle.
gtp_newlink() links the device to a list in dev_net(dev) instead of
src_net, where a udp tunnel socket is created.
Even when src_net is removed, the device stays alive on dev_net(dev).
Then, removing src_net triggers the splat below. [0]
In this example, gtp0 is created in ns2, and the udp socket is created
in ns1.
ip netns add ns1
ip netns add ns2
ip -n ns1 link add netns ns2 name gtp0 type gtp role sgsn
ip netns del ns1
Let's link the device to the socket's netns instead.
Now, gtp_net_exit_batch_rtnl() needs another netdev iteration to remove
all gtp devices in the netns.
[0]:

Title
exfat: fix the infinite loop in exfat_readdir()
Summary
In the Linux kernel, the following vulnerability has been resolved:
exfat: fix the infinite loop in exfat_readdir()
If the file system is corrupted so that a cluster is linked to
itself in the cluster chain, and there is an unused directory
entry in the cluster, 'dentry' will not be incremented, causing
condition 'dentry < max_dentries' unable to prevent an infinite
loop.
This infinite loop causes s_lock not to be released, and other
tasks will hang, such as exfat_sync_fs().
This commit stops traversing the cluster chain when there is unused
directory entry in the cluster to avoid this infinite loop.
Severity
No CVSS data available.

net_sched: cls_flow: validate TCA_FLOW_RSHIFT attribute
Summary
In the Linux kernel, the following vulnerability has been resolved:
net_sched: cls_flow: validate TCA_FLOW_RSHIFT attribute
syzbot found that TCA_FLOW_RSHIFT attribute was not validated.
Right shitfing a 32bit integer is undefined for large shift values.
UBSAN: shift-out-of-bounds in net/sched/cls_flow.c:329:23
shift exponent 9445 is too large for 32-bit type 'u32' (aka 'unsigned int')

Summary
In the Linux kernel, the following vulnerability has been resolved:
sched: sch_cake: add bounds checks to host bulk flow fairness counts
Even though we fixed a logic error in the commit cited below, syzbot
still managed to trigger an underflow of the per-host bulk flow
counters, leading to an out of bounds memory access.
To avoid any such logic errors causing out of bounds memory accesses,
this commit factors out all accesses to the per-host bulk flow counters
to a series of helpers that perform bounds-checking before any
increments and decrements. This also has the benefit of improving
readability by moving the conditional checks for the flow mode into
these helpers, instead of having them spread out throughout the
code (which was the cause of the original logic error).
As part of this change, the flow quantum calculation is consolidated
into a helper function, which means that the dithering applied to the
ost load scaling is now applied both in the DRR rotation and when a
sparse flow's quantum is first initiated. The only user-visible effect
of this is that the maximum packet size that can be sent while a flow
stays sparse will now vary with +/- one byte in some cases. This should
not make a noticeable difference in practice, and thus it's not worth
complicating the code to preserve the old behaviour.

Its possible that two threads call tcp_v6_do_rcv()/sk_forward_alloc_add()
concurrently when sk->sk_state == TCP_LISTEN with sk->sk_lock unlocked,
which triggers a data-race around sk->sk_forward_alloc:

The skb_clone_and_charge_r() should not be called in tcp_v6_do_rcv() when
sk->sk_state is TCP_LISTEN, it happens later in tcp_v6_syn_recv_sock().
Fix the same issue in dccp_v6_do_rcv().

"value": "AV:N - The vulnerable code is in the IPv6 TCP receive path (`tcp_v6_rcv()` \u2192 `tcp_v6_do_rcv()`), executed directly on inbound SYN packets from any remote peer; a remote attacker reaches it by sending TCP/IPv6 segments to a listening socket. The same defect exists in the DCCP IPv6 receive path.\nAC:L - The attacker controls both sides of the race by sending a burst of concurrent SYNs from different source ports/addresses, which RSS/RPS distributes across CPUs that all enter `tcp_v6_do_rcv()` on the same listener with no socket lock held. No memory layout, timing window outside attacker influence, or victim state is required, and syzkaller reproduces it routinely.\nPR:N - The racing code runs while processing a SYN on a listening socket, entirely before connection establishment or any authentication, so no credentials of any kind are needed. Setting the `IPV6_RECV*` option that arms the path is done by the victim server (or by an unprivileged local user on their own listener), not by the attacker.\nUI:N - Triggering requires only that packets be sent to an already-listening socket; no action by any local user or administrator is needed.\nS:U - The corrupted state (`sk-\u003esk_forward_alloc`, `tcp_memory_allocated`, memcg skmem counters) and the resulting warning/panic are all within the kernel\u0027s own security authority, with no crossing into a hypervisor, IOMMU, or other separate authority.\nC:N - The defect is a non-atomic read-modify-write on integer accounting counters; it produces no out-of-bounds read, no use-after-free, and no path by which memory contents or kernel pointers are disclosed to the attacker.\nI:N - No attacker-controlled data is written and no memory corruption primitive is created \u2014 only the socket\u0027s own memory-accounting counters become inconsistent, which is not a modification of protected data or control flow.\nA:H - The imbalance trips `WARN_ON_ONCE(sk_forward_alloc_get(sk))` in `inet_sock_destruct()` from softirq context, which is an immediate kernel panic on `panic_on_warn` systems, and the over-reclaim corrupts the global `tcp_memory_allocated` counter and memcg skmem accounting, breaking system-wide TCP memory limits (unbounded growth toward OOM, or permanent memory pressure across all TCP sockets). It is repeatable at will by an unauthenticated remote attacker."

Title
Squashfs: check the inode number is not the invalid value of zero
Summary
In the Linux kernel, the following vulnerability has been resolved:
Squashfs: check the inode number is not the invalid value of zero
Syskiller has produced an out of bounds access in fill_meta_index().
That out of bounds access is ultimately caused because the inode
has an inode number with the invalid value of zero, which was not checked.
The reason this causes the out of bounds access is due to following
sequence of events:
1. Fill_meta_index() is called to allocate (via empty_meta_index())
and fill a metadata index. It however suffers a data read error
and aborts, invalidating the newly returned empty metadata index.
It does this by setting the inode number of the index to zero,
which means unused (zero is not a valid inode number).
2. When fill_meta_index() is subsequently called again on another
read operation, locate_meta_index() returns the previous index
because it matches the inode number of 0. Because this index
has been returned it is expected to have been filled, and because
it hasn't been, an out of bounds access is performed.
This patch adds a sanity check which checks that the inode number
is not zero when the inode is created and returns -EINVAL if it is.
