CVE-2026-45199
GPU DDK - rgxfw_to_ptr() does not reject FW private data pointers
Reported by imaginationtech · Published August 21, 2026
Kernel software installed and running inside a Guest VM may post improper commands to the GPU Firmware to trigger a write of data outside the Guest's virtualised GPU memory. Software installed and run under a Guest VM can send commands to the GPU which result in out of bounds memory accesses. These can be used to escalate privileges.
