CVE-2024-43901

A NULL pointer dereference vulnerability was found in the AMD Display (drm/amd/display) subsystem of the Linux kernel when users attempt to access the DTN log. When the command (cat /sys/kernel/debug/dri/0/amdgpu_dm_dtn_log ) to access the DTN log is run, the code attempts to read the gamut remap information. If this information has not been initialized, it will result in a NULL pointer dereference, leading to a kernel panic. This flaw allows an attacker to cause kernel panic, which leads the system to crash or become unresponsive.
