Make KSMA Great Again: The Art of Rooting Android Devices by GPU MMU Features

With more and more hardware and software mitigations, rooting Android 13 devices now requires better bugs and more advanced exploitation techniques. Five years ago, I introduced the Kernel Space Mirroring Attack (KSMA) exploitation technique[1], which is based on the CPU MMU features. Similar to the CPU, the GPU of an Android device also contains an MMU which helps to efficiently manage and access the system memory. From an attacker's view, developing a similar exploitation technique is attractive because there are …
