CVE-2022-32616

Local privilege escalation via uninitialized ISP data

Published Nov 8, 2022 · Updated May 1, 2025

Out-of-bounds write in MediaTek ISP software for Android 12.0 allows local users with System privileges to escalate privileges. The ISP component consumes uninitialized data during an undisclosed operation and writes beyond the intended buffer; MediaTek has not identified the affected function or input. The attack requires existing System execution privileges and no user interaction, and successful exploitation elevates local privileges on devices using MT6983, MT8871, or MT8891 chipsets.
