Further Hardening Android GPUs
Brief

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.
While finding and fixing individual bugs is crucial, and progress continues on eliminating them entirely , making them unreachable by restricting attack surface is another effective and often faster way to improve security. This post details our efforts in partnership with Arm to further harden the GPU by reducing the driver's attack surface.
