CVE-2024-39481

Kernel crash via non-data media link traversal

Published Jul 5, 2024 · Updated Aug 5, 2026

Denial of service in the Linux media controller allows local users to crash the kernel by starting a pipeline with an ancillary link. The media_pipeline_start graph walk follows every link as if it connected pads, so an ancillary link reaches invalid traversal state instead of being skipped. Exploitation requires local low-privilege access and a media topology containing the non-data link; the documented consequence is a kernel crash.
