CVE-2024-42120

CVE-2024-42120 pertains to the Linux kernel, specifically a vulnerability in the DRM AMD display code. The issue is an OVERRUN caused by accessing the pipe_ctx array without validating an index against its MAX_PIPES size, which could lead to out-of-bounds access in the vblank handling path. The d...

CVE-2024-42120 drm/amd/display: Check pipe offset before setting vblank

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check pipe offset before setting vblank pipectx has a size of MAXPIPES so checking its index before accessing the array. This fixes an OVERRUN issue reported by Coverity...

CVE-2024-42119

The CVE-2024-42119 entry concerns a Linux kernel issue in drm/amd/display where the code pathSkip finding free audio for unknown engine_id (ENGINE_ID_UNKNOWN = -1) could be mishandled as an array index. The root cause is that ENGINE_ID_UNKNOWN is -1 and uninitialized, leading to unnecessary free ...

CVE-2024-42118 drm/amd/display: Do not return negative stream id for array

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Do not return negative stream id for array WHY resourcestreamtostreamidx returns an array index and it return -1 when not found; however, -1 is not a valid array index number. HOW When this happens, call ASSERT,...

CVE-2024-42118

CVE-2024-42118 – Linux kernel / drm/amd display : The issue arises in resource_stream_to_stream_idx where an array index can be -1 if not found. The code currently asserts and then returns 0, preventing a negative index and thereby avoiding an OVERRUN and NEGATIVE_RETURNS. Connected sources ident...

CVE-2024-42117

CVE-2024-42117 affects the Linux kernel DRM/AMD display path. The root cause was that find_disp_cfg_idx_by_plane_id and find_disp_cfg_idx_by_stream_id could return -1 and that value was used as an index, causing overrun/negative-return conditions. The fix is to return a valid positive index or ta...
