NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_14_21-150500_55_88-default package and not the kernel-livepatch-5_14_21-150500_55_88-default package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

drm/vc4: Stop the active perfmon before being destroyed

Upon closing the file descriptor, the active performance monitor is not stopped. Although all perfmons are destroyed in vc4_perfmon_close_file(), the active performance monitor's pointer (vc4-&gt;active_perfmon) is still retained.

If we open a new file descriptor and submit a few jobs with performance monitors, the driver will attempt to stop the active performance monitor using the stale pointer in vc4-&gt;active_perfmon. However, this pointer is no longer valid because the previous process has already terminated, and all performance monitors associated with it have been destroyed and freed.

To fix this, when the active performance monitor belongs to a given process, explicitly stop it before destroying and freeing it.
