Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: wifi: rtw89: pci: validate sequence number of TX release report Hardware rarely reports abnormal sequence number in TX release report, which will access out-of-bounds of wd_ring->pages array, causing NULL pointer dereference. BUG: kernel NULL pointer dereference, address: 0000000000000000 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: 0000 [#1] PREEMPT SMP NOPTI CPU: 1 PID: 1085 Comm: irq/129-rtw89_p Tainted: G S U 6.1.145-17510-g2f3369c91536 #1 (HASH:69e8 1) Call Trace: <IRQ> rtw89_pci_release_tx+0x18f/0x300 [rtw89_pci (HASH:4c83 2)] rtw89_pci_napi_poll+0xc2/0x190 [rtw89_pci (HASH:4c83 2)] net_rx_action+0xfc/0x460 net/core/dev.c:6578 net/core/dev.c:6645 net/core/dev.c:6759 handle_softirqs+0xbe/0x290 kernel/softirq.c:601 ? rtw89_pci_interrupt_threadfn+0xc5/0x350 [rtw89_pci (HASH:4c83 2)] __local_bh_enable_ip+0xeb/0x120 kernel/softirq.c:499 kernel/softirq.c:423 </IRQ> <TASK> rtw89_pci_interrupt_threadfn+0xf8/0x350 [rtw89_pci (HASH:4c83 2)] ? irq_thread+0xa7/0x340 kernel/irq/manage.c:0 irq_thread+0x177/0x340 kernel/irq/manage.c:1205 kernel/irq/manage.c:1314 ? thaw_kernel_threads+0xb0/0xb0 kernel/irq/manage.c:1202 ? irq_forced_thread_fn+0x80/0x80 kernel/irq/manage.c:1220 kthread+0xea/0x110 kernel/kthread.c:376 ? synchronize_irq+0x1a0/0x1a0 kernel/irq/manage.c:1287 ? kthread_associate_blkcg+0x80/0x80 kernel/kthread.c:331 ret_from_fork+0x1f/0x30 arch/x86/entry/entry_64.S:295 </TASK> To prevent crash, validate rpp_info.seq before using.
