Description
A NULL pointer dereference issue was found in the AMD Display (drm/amd/display) subsystem of the Linux kernel in amdgpu_dm.c. If an attacker can manipulate the input to functions that may not have proper NULL checks, they could trigger a situation where the system dereferences a NULL pointer, leading to system crashes and loss of availability, requiring a reboot to restore the system. This issue could also disrupt services dependent on the GPU.
