Local privilege escalation via unchecked display write
Published Mar 2, 2026 · Updated Mar 2, 2026
Out-of-bounds write in MediaTek Display Driver on Android 14.0, 15.0, and 16.0 allows local users with System privilege to escalate privileges. The display subcomponent performs an out-of-bounds write because a bounds check is missing; MediaTek has not disclosed the affected function or input path. The attack requires prior System-level access, needs no user interaction, and yields higher local privilege on an affected MediaTek chipset.
