Linux Kernel NULL Pointer Dereference Vulnerability in DRM/MSM/DPU Component

A vulnerability in the Linux kernel's DRM/MSM/DPU component could lead to a NULL pointer dereference. This issue arises when the plane state is printed without a corresponding atomic check, causing the pipe's SSPP to be unassigned. The vulnerability has been addressed by adding a validation check to ensure the pipe state prints are only executed when a proper atomic check has been performed.

Impact

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