Summary
CVE-2024-49913 affecting package kernel for versions less than 6.6.56.1-5
Details

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Add null check for toppipetoprogram in commitplanesforstream

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 commitplanesforstream() error: we previously assumed 'toppipetoprogram' could be null (see line 3906)
