Local privilege escalation via incorrect AIE bounds check
Published Sep 6, 2022 · Updated Aug 3, 2024
Out-of-bounds write in MediaTek AIE on affected Android 12.0 chipsets allows local users with System privileges to elevate privileges. The AIE component applies an incorrect bounds check before writing to a buffer, permitting a write beyond the intended boundary. Exploitation requires existing System execution privileges and no user interaction; MediaTek has not disclosed the affected function or resulting privilege level.
