Kernel memory corruption via stale DRM pointer dereference
Published Jan 19, 2025 · Updated Aug 5, 2026
Use-after-free in the MediaTek DRM driver in Linux 6.4 through 6.13-rc6 allows local users to crash the kernel during shutdown. mtk_drm_bind leaves a freed drm_device pointer in secondary DRM private data when mtk_drm_kms_init fails, and drm_atomic_helper_shutdown later dereferences it. Exploitation requires an affected MediaTek mt8188 or mt8195 system, a failed DRM initialization, local reboot access, and no victim interaction.
