CVE-2022-50187: Linux kernel network driver can crash on device start
CVE-2022-50187 · published 1 year ago
Summary
The Linux kernel's ath11k network driver could crash when the system tries to open the device before certain internal timers are ready. This can cause the whole system to stop responding. Installing the latest kernel updates that include the fix will prevent the crash.

ath11k: fix netdev open race
In the Linux kernel, the following vulnerability has been resolved: ath11k: fix netdev open race Make sure to allocate resources needed before registering the device. This specifically avoids having a racing open() trigger a BUG_ON() in mod_timer() when ath11k_mac_op_start() is called before the mon_reap_timer as been set up. I did not see this issue with next-20220310, but I hit it on every probe with next-20220511. Perhaps some timing changed in between. Here's the backtrace: [ 51.346947] kernel BUG at kernel/time/timer.c:990! [ 51.346958] Internal error: Oops - BUG: 0 [#1] PREEMPT SMP ...
