GPU Memory Arbitrary Write in Kernel

Publication date: 2026-06-01

Last updated on: 2026-06-01

Assigner: imaginationtech

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.

Executive Summary

This vulnerability involves kernel software running inside a Guest or Host virtual machine that can send improper commands to the GPU firmware. Due to a logic error in address translation, a compromised Host kernel can perform arbitrary writes to the GPU firmware memory, writing data outside the intended GPU memory area.

Impact Analysis

The vulnerability allows a compromised Host kernel to write arbitrary data to GPU firmware memory. This could lead to unauthorized modification of firmware, potentially causing system instability, security breaches, or enabling further attacks by corrupting GPU operations.
