In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add null check for head_pipe in dcn201_acquire_free_pipe_for_layer
This commit addresses a potential null pointer dereference issue in the
dcn201_acquire_free_pipe_for_layer function. The issue could occur
when head_pipe is null.
The fix adds a check to ensure head_pipe is not null before asserting
it. If head_pipe is null, the function returns NULL to prevent a
potential null pointer dereference.
Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/resource/dcn201/dcn201_resource.c:1016 dcn201_acquire_free_pipe_for_layer() error: we previously assumed 'head_pipe' could be null (see line 1010)
