A fix is available and has been applied in the Linux kernel commits identified by the fixedVersions hashes. Users should update to a kernel version including these fixes to remediate the issue.

Description

A vulnerability in the Linux kernel's drm/vc4 driver was fixed by properly draining the hangcheck timer and related work on V3D unbind. The flaw allowed timer callbacks to access freed memory due to the timer not being stopped before the device was unbound and freed.
