Local privilege escalation via logic-error out-of-bounds write
Published May 15, 2023 · Updated Jan 24, 2025
Out-of-bounds write in MediaTek Widevine on Android 11.0 and 12.0 allows local users with System privileges to escalate privileges. A logic error in the Widevine component permits an out-of-bounds memory write, but MediaTek has not disclosed the affected function, input, or incorrect operation. Exploitation requires existing System execution privileges, is local, and needs no user interaction; the resulting privilege boundary is not disclosed.
