CVE-2022-20598

Local privilege escalation via sec_media_protect integer overflow

Published Dec 16, 2022 · Updated Apr 18, 2025

Integer overflow in sec_media_protect in Google Pixel Android kernel firmware allows local users to gain secure-mode MFC Core privileges. The media.c routine fails to prevent an integer overflow during media protection, but Google has not disclosed the triggering input or arithmetic operation. Exploitation requires local low-privileged execution, needs no user interaction, and can elevate code into the secure-mode MFC Core.
