CVE-2026-34193
GPU DDK - Arbitrary write via UFO updates due insufficient pointer validation in rgxfw_to_ptr()
Description
Kernel software installed and running inside a Guest/Host VM may post improper commands to the GPU Firmware to trigger a write of data outside the intended GPU memory. A logic error in the address translation allowed a compromised Host (Kernel) to perform arbitrary writes to firmware memory.
