CVE-2026-68233 (opens in a new tab)Amendment
The Centos security team deemed this advisory irrelevant for Centos:8.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-devel package and not the kernel-devel package as distributed by Centos.
In the Linux kernel, the following vulnerability has been resolved:
drm/vc4: Shut down BO cache timer before teardown
The BO cache timer callback schedules time_work, and time_work can rearm the timer through vc4_bo_cache_free_old().
vc4_bo_cache_destroy() deletes the timer and then cancels the work, which does not break that cycle: the work being cancelled can rearm the timer, and the timer then queues work again after teardown.
Use timer_shutdown_sync() instead, so the timer cannot be rearmed and the cycle ends with cancel_work_sync().
