Local privilege escalation via unchecked display DRM write
Published Dec 4, 2023 · Updated Aug 2, 2024
An out-of-bounds write in MediaTek display DRM on Android 12.0 and 13.0 allows local users with System execution privileges to escalate locally. The display DRM component writes beyond an intended buffer because a required bounds check is missing; MediaTek has not disclosed the affected function or input path. Exploitation requires existing System execution privileges but no user interaction, and successful exploitation executes in a more privileged local context.
