CVE-2024-50214

Service interruption via unreleased DRM display modes

Published Nov 9, 2024 · Updated May 11, 2026

Memory leakage in the Linux 6.11 DRM connector test module allows local users to exhaust kernel memory through module reload cycles. drm_display_mode_from_cea_vic() returns a mode allocated by drm_mode_duplicate(), but the test stores it without releasing it before module teardown. Reaching the flaw requires local access and loading and unloading the DRM KUnit test module; repeated cycles consume kernel memory and can interrupt service.
