CVE-2024-50201

Driver initialization warnings via incomplete clone bitmask

Published Nov 8, 2024 · Updated May 11, 2026

Improper encoder clone-mask handling in Linux 5.8 through affected branches allows local users to trigger driver initialization warnings. In drivers/gpu/drm/radeon/radeon_encoders.c, Radeon encoder setup omits each encoder's own bit from possible_clones, so DRM validation reports a bogus mask and emits a kernel warning. Reachability requires a locally accessible system using the affected Radeon driver and encoder path; published evidence demonstrates initialization warnings but does not document a panic or data compromise.
