CVE-2024-26874

Kernel crash via unlocked page-flip event race

Published Apr 17, 2024 · Updated May 11, 2026

NULL pointer dereference in Linux 4.7 and later allows local users to crash systems using the MediaTek DRM display driver. A race lets mtk_drm_crtc_atomic_flush set pending_needs_vblank after mtk_drm_finish_page_flip clears the event, so a later interrupt dereferences NULL. Exploitation requires low-privileged local access, high-complexity timing, and an affected MediaTek display path; the reported impact is a system crash only.
