Linux Kernel V3D Driver Null Pointer Dereference Vulnerability

Vulnerability

A null pointer dereference vulnerability has been identified in the Linux kernel's V3D graphics driver. This issue arises when the 'perfmon' pointer is null, leading to a warning after the pointer has already been dereferenced. The vulnerability has been addressed by ensuring that 'perfmon' is checked for nullity before being dereferenced.

Impact

Exploitation of this vulnerability could lead to a null pointer dereference, causing a crash or undefined behavior in the kernel.
