Local privilege escalation via audio IPI overwrite
Published Sep 6, 2022 · Updated Aug 3, 2024
Out-of-bounds write in MediaTek audio IPI on Android 11.0, Android 12.0, and Yocto 3.1 allows local users to elevate privileges. An incorrect bounds check permits audio IPI processing to write beyond the intended buffer, although the specific buffer is undisclosed. Exploitation requires existing System execution privileges but no user interaction; MediaTek does not identify the resulting elevated privilege level.
