CVE-2024-46775

Service interruption via unchecked display return values

Published Sep 18, 2024 · Updated May 11, 2026

Unchecked-return handling in Linux 4.15 through 6.10.9 allows local users to interrupt service through AMD display-driver operations. dc_dmub_srv_cmd_run_list continues after an idle-wait failure, while visual-confirmation, watermark, and link-training paths use results without confirming that their producers succeeded. Reachability requires local access and the affected AMD display stack; public records identify no specific trigger or whether interruption manifests as a hang or crash.
