Vulnerability from cvelistv5 – Published: 2026-08-21 03:36 – Updated: 2026-08-25 03:56

Title

GPU DDK - rgxfw_to_ptr() does not reject FW private data pointers

Summary

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.
