CVE-2025-68180

Kernel crash via unchecked display timing pointer

Published Dec 16, 2025 · Updated Dec 16, 2025

NULL pointer dereference in the Linux AMD display debugfs interface allows local users to crash the kernel by reading odm_combine_segments. The odm_combine_segments_show function dereferences pipe_ctx->stream_res.tg after that timing-generator pointer has been destroyed for an inactive connector. The trigger requires a connected but inactive connector and debugfs access; the demonstrated read ran as UID 0 and produced a kernel Oops.
