Posted by Liz Prucka, Hamzeh Zawawy, Rishika Hooda, Android Security and Privacy Team Last year, Google's Android Red Team partnered with Arm to conduct an in-depth security analysis of the Mali GPU, a component used in billions of Android devices worldwide. This collaboration was a significant step in proactively identifying and fixing vulnerabilities in the GPU software and firmware stack. This post details our efforts in partnership with Arm to further harden the GPU by reducing the driver's attack surface. The Growing Threat: Why GPU Security Matters The Graphics Processing Unit (GPU) has become a critical and attractive target for attackers due to its complexity and privileged access to the system.
We partnered with Arm to conduct an analysis of the Mali driver, used on approximately 45% of Android devices.
