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

Explore the advanced exploitation technique for rooting Android 13 devices in this 35-minute Black Hat conference talk. Delve into the Kernel Space Mirroring Attack (KSMA) based on GPU MMU features, a method that bypasses current hardware and software mitigations. Learn how the speaker, Yong Wang, adapts the CPU-based KSMA technique to leverage GPU architecture, exploiting the lack of existing mitigations in this area. Gain insights into the challenges of working without a GPU Architecture Reference Manual and discover the potential of this novel approach for Android device rooting. This presentation offers valuable knowledge for security researchers and Android developers interested in understanding and addressing vulnerabilities in mobile device security.
