In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add NULL check for function pointer in dcn20setoutputtransferfunc This commit adds a null check for the setoutputgamma function pointer in the dcn20setoutputtransferfunc function. Previously, setoutputgamma was...

CVE-2024-49912

The CVE-2024-49912 entry concerns a Linux kernel DRM/AMD display issue. A null pointer dereference risk existed in drm/amd/display within planes_changed_for_existing_stream when stream_status could be null. The published fix adds a null check for stream_status in planes_changed_for_existing_strea...

CVE-2024-49908

CVE-2024-49908: In the Linux kernel, the AMDGPU display driver (amdgpu_dm) had a missing null check for theafb in amdgpu_dm_update_cursor, risking a null pointer dereference. The fix adds a null check and moves the check to the point of use (line where afb is accessed). Affects drm/amd/display co...

CVE-2024-49907 drm/amd/display: Check null pointers before using dc->clk_mgr

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check null pointers before using dc-clkmgr WHY & HOW dc-clkmgr is null checked previously in the same function, indicating it might be null. Passing "dc" to "dc-hwss.applyidlepoweroptimizations", which dereferenc...
