CVE-2022-49485
In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Fix null pointer dereference of pointer perfmon In the unlikely event that pointer perfmon is null the WARN_ON return path occurs after the pointer has already been deferenced.
Does this matter?
Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.
