CVE-2023-53388

Kernel panic via dangling DRM device pointer

Published Sep 18, 2025 · Updated Sep 18, 2025

Use-after-free in the MediaTek DRM driver in the Linux kernel allows local users to trigger a kernel panic during system suspend. When mtk_drm_bind() fails, drm_dev_put() frees the drm_device while the private object retains its pointer, which mtk_drm_sys_prepare() later passes to DRM. Reachability requires a MediaTek DRM bind failure followed by system suspend; dereferencing the stale device pointer then crashes the kernel.
