Summary
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add null check for top_pipe_to_program in commit_planes_for_stream This commit addresses a null pointer dereference issue in the `commit_planes_for_stream` function at line 4140. The issue could occur when `top_pipe_to_program` is null. The fix adds a check to ensure `top_pipe_to_program` is not null before accessing its stream_res. This prevents a null pointer dereference. Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc.c:4140 commit_planes_for_stream() error: we previously assumed 'top_pipe_to_program' could be null (see line 3906)
