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 bpftool package and not the bpftool 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().
