CVE-2024-49913 Description
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)
