Type:
CWE-476
NULL Pointer Dereference
Publication date:

Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/amd/display: Add null check for top_pipe_to_program in commit_planes_for_stream<br />
<br />
This commit addresses a null pointer dereference issue in the<br />
`commit_planes_for_stream` function at line 4140. The issue could occur<br />
when `top_pipe_to_program` is null.<br />
<br />
The fix adds a check to ensure `top_pipe_to_program` is not null before<br />
accessing its stream_res. This prevents a null pointer dereference.<br />
<br />
Reported by smatch:<br />
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc.c:4140 commit_planes_for_stream() error: we previously assumed &#39;top_pipe_to_program&#39; could be null (see line 3906)
