Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A NULL pointer dereference vulnerability has been resolved in the Linux kernel, specifically in the drm/amd/display component. The issue occurs when the color log tries to read the gamut remap information from DCN401, which is not initialized in the dcn401 dpp funcs, leading to a null pointer dereference. This vulnerability is addressed by adding a proper guard to access the gamut remap callback in case the specific ASIC did not implement this function. The vulnerability can be triggered by running the command cat /sys/kernel/debug/dri/0/amdgpu dm dtn log.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
