CVE-2025-71141

Service interruption via uninitialized tilcdc cleanup

Published Jan 14, 2026 · Updated Jan 14, 2026

Improper cleanup in the Linux kernel tilcdc driver allows local users to interrupt service during deferred device probing. tilcdc_fini() unconditionally calls drm_kms_helper_poll_fini() and drm_atomic_helper_shutdown() when probe deferral prevented device registration. Triggering requires local low-privileged access and a tilcdc probe-deferral path; the exact service-interruption failure mode is not published.
