Android Arm Mali GPU Arbitrary Code Execution
Posted Jun 11, 2023
Authored by Man Yue Mo, GitHub Security Lab

Proof of concept exploit for a memory corruption vulnerability in the Arm Mali GPU kernel driver that was reported in January of 2022. The bug can be used to gain arbitrary kernel code execution from the untrusted app domain, which is then used to disable SELinux and gain root. The exploit is tested on the Google Pixel 6 and supports patch levels from November 2021 to February 2022. It is easy to add support for other firmware by changing a few image offsets.
