Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.4.5
Description
The issue is related to a use-after-free condition in the Linux kernel, specifically in the
drm atomic state init function within drivers/gpu/drm/drm atomic.c. This occurs due to a race condition between a nonblocking atomic commit and a driver unload, potentially allowing an attacker to execute arbitrary code.Recommendations
For Linux kernel versions prior to 6.4.5, update to version 6.4.5 or later to resolve the issue.
As a temporary workaround, consider restricting access to the
drm atomic state init function until a patch is available.Fix
