GHSA-fg46-5p85-h39f

In the Linux kernel, the following vulnerability has been resolved:

vmci: Prevent the dispatching of uninitialized payloads

The reproducer executes the host's unlocked_ioctl call in two different tasks. When init_context fails, the struct vmci_event_ctx is not fully initialized when executing vmci_datagram_dispatch() to send events to all vm contexts. This affects the datagram taken from the datagram queue of its context by another task, because the datagram payload is not initialized according to the size payload_size, which causes the kernel data to leak to the user space.

Before dispatching the datagram, and before setting the payload content, explicitly set the payload content to 0 to avoid data leakage caused by incomplete payload initialization.

OESA-2025-2118 — kernel security update

Affected: openEuler:22.03-LTS-SP3: kernel

The Linux Kernel, the operating system core itself. Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nf_tables: avoid skb access on nf_stolen

When verdict is NF_STOLEN, the skb might have been freed.

When tracing is enabled, this can result in a use-after-free: 1. access to skb->nf_trace 2. access to skb->mark 3. computation of trace id 4. dump of packet payload

To avoid 1, keep a cached copy of skb->nf_trace in the trace state struct. Refresh this copy whenever verdict is != STOLEN.

Avoid 2 by skipping skb->mark access if verdict is STOLEN.

3 is avoided by precomputing the trace id.

Only dump the packet when verdict is not "STOLEN".(CVE-2022-49622)

In the Linux kernel, the following vulnerability has been resolved:

nfsd: release svc_expkey/svc_export with rcu_work

The last reference for `cache_head` can be reduced to zero in `c_show` and `e_show`(using `rcu_read_lock` and `rcu_read_unlock`). Consequently, `svc_export_put` and `expkey_put` will be invoked, leading to two issues:

1. The `svc_export_put` will directly free ex_uuid. However, `e_show`/`c_show` will access `ex_uuid` after `cache_put`, which can trigger a use-after-free issue, shown below.
