Title
ionic: fix kernel panic in XDP_TX action
Summary
In the Linux kernel, the following vulnerability has been resolved: ionic: fix kernel panic in XDP_TX action In the XDP_TX path, ionic driver sends a packet to the TX path with rx page and corresponding dma address. After tx is done, ionic_tx_clean() frees that page. But RX ring buffer isn't reset to NULL. So, it uses a freed page, which causes kernel panic. BUG: unable to handle page fault for address: ffff8881576c110c PGD 773801067 P4D 773801067 PUD 87f086067 PMD 87efca067 PTE 800ffffea893e060 Oops: Oops: 0000 [#1] PREEMPT SMP DEBUG_PAGEALLOC KASAN NOPTI CPU: 1 PID: 25 Comm: ksoftirqd/1 Not tainted 6.9.0+ #11 Hardware name: ASUS System Product Name/PRIME Z690-P D4, BIOS 0603 11/01/2021 RIP: 0010:bpf_prog_f0b8caeac1068a55_balancer_ingress+0x3b/0x44f Code: 00 53 41 55 41 56 41 57 b8 01 00 00 00 48 8b 5f 08 4c 8b 77 00 4c 89 f7 48 83 c7 0e 48 39 d8 RSP: 0018:ffff888104e6fa28 EFLAGS: 00010283 RAX: 0000000000000002 RBX: ffff8881576c1140 RCX: 0000000000000002 RDX: ffffffffc0051f64 RSI: ffffc90002d33048 RDI: ffff8881576c110e RBP: ffff888104e6fa88 R08: 0000000000000000 R09: ffffed1027a04a23 R10: 0000000000000000 R11: 0000000000000000 R12: ffff8881b03a21a8 R13: ffff8881589f800f R14: ffff8881576c1100 R15: 00000001576c1100 FS: 0000000000000000(0000) GS:ffff88881ae00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: ffff8881576c110c CR3: 0000000767a90000 CR4: 00000000007506f0 PKRU: 55555554 Call Trace: <TASK> ? __die+0x20/0x70 ? page_fault_oops+0x254/0x790 ? __pfx_page_fault_oops+0x10/0x10 ? __pfx_is_prefetch.constprop.0+0x10/0x10 ? search_bpf_extables+0x165/0x260 ? fixup_exception+0x4a/0x970 ? exc_page_fault+0xcb/0xe0 ? asm_exc_page_fault+0x22/0x30 ? 0xffffffffc0051f64 ? bpf_prog_f0b8caeac1068a55_balancer_ingress+0x3b/0x44f ? do_raw_spin_unlock+0x54/0x220 ionic_rx_service+0x11ab/0x3010 [ionic 9180c3001ab627d82bbc5f3ebe8a0decaf6bb864] ? ionic_tx_clean+0x29b/0xc60 [ionic 9180c3001ab627d82bbc5f3ebe8a0decaf6bb864] ? __pfx_ionic_tx_clean+0x10/0x10 [ionic 9180c3001ab627d82bbc5f3ebe8a0decaf6bb864] ? __pfx_ionic_rx_service+0x10/0x10 [ionic 9180c3001ab627d82bbc5f3ebe8a0decaf6bb864] ? ionic_tx_cq_service+0x25d/0xa00 [ionic 9180c3001ab627d82bbc5f3ebe8a0decaf6bb864] ? __pfx_ionic_rx_service+0x10/0x10 [ionic 9180c3001ab627d82bbc5f3ebe8a0decaf6bb864] ionic_cq_service+0x69/0x150 [ionic 9180c3001ab627d82bbc5f3ebe8a0decaf6bb864] ionic_txrx_napi+0x11a/0x540 [ionic 9180c3001ab627d82bbc5f3ebe8a0decaf6bb864] __napi_poll.constprop.0+0xa0/0x440 net_rx_action+0x7e7/0xc30 ? __pfx_net_rx_action+0x10/0x10

A remote attacker anywhere reachable by the NIC (e.g. an internet-facing XDP load balancer, the driver\u0027s primary XDP_TX use case) triggers it by sending packets.\nAC:L - There is no race to win and no dependence on memory layout the attacker cannot influence \u2014 every packet the XDP program answers with XDP_TX deterministically leaks the RX slot, and the attacker controls the packet contents that drive that verdict. Repeating it drains and corrupts the RX ring reliably.\nPR:N - The path from packet arrival to ionic_run_xdp() contains no authentication, socket binding, or capability check whatsoever; it executes in softirq/NAPI context before any protocol-level authorization. Attaching the XDP program is an administrator\u0027s prior configuration, not an attacker prerequisite.\nUI:N - No local user action is needed \u2014 the bug fires automatically during NAPI processing of an attacker-sent packet.\nS:U - The use-after-free, the stale DMA write, and the resulting corruption all occur within the kernel\u0027s own memory and security authority, with no crossing into a hypervisor or other security scope.\nC:H - The freed page stays in the RX ring, so its contents \u2014 by then reallocated to arbitrary kernel objects \u2014 are read by bpf_prog_run_xdp() and copied into skbs that are delivered up the stack or retransmitted, exposing kernel memory to the attacker. Use-after-free reads of this kind constitute a high-impact disclosure primitive.\nI:H - The NIC continues DMA-ing attacker-controlled packet payload into the page after it has been freed and recycled by the page allocator, giving a remote write of controlled data into arbitrary reallocated kernel objects; the stale slot also yields a double free via ionic_rx_page_free()/ionic_rx_empty().\nA:H - The fix is titled \"fix kernel panic in XDP_TX action\" and the commit carries a reproduced oops (page fault in the BPF program from ionic_rx_service), i.e. a repeatable remote kernel crash."
