Kernel code execution via GPU ringbuffer corruption
Published Feb 7, 2020 · Updated Aug 4, 2024
Privilege escalation in Qualcomm Snapdragon GPU drivers on listed chipsets allows local users to execute code in the kernel. A writable shared scratch buffer lets user-supplied GPU commands corrupt the ringbuffer read pointer, overwrite queued commands, disable protected mode, and replace TTBR0 for arbitrary physical-memory access. Access from an Android application sandbox is sufficient, and successful exploitation grants kernel-level code execution.
