CVE-2023-52911

Reboot-time kernel crash via missing KMS object

Published Aug 21, 2024 · Updated May 23, 2026

NULL pointer dereference in Linux 6.1 through 6.1.6 allows local users to crash the kernel during headless Adreno system reboot. The msm DRM shutdown routine calls drm_atomic_helper_shutdown without checking whether the headless configuration created a KMS object, so msm_atomic_commit_tail dereferences a null pointer. Reachability requires a system using the msm Adreno driver without display hardware and a reboot or shutdown; the observed consequence is a kernel oops that interrupts orderly restart.
