Local privilege escalation via display integer overflow
Published Nov 6, 2023 · Updated Apr 25, 2025
Out-of-bounds write in MediaTek display software for Android 11.0 through 13.0 allows local users to escalate to system privileges. An integer overflow in the display component produces an out-of-bounds write, although MediaTek does not identify the affected function or input. Exploitation requires existing System execution privileges but no user interaction, and successful exploitation reaches a more privileged context.
