# CVE-2026-74915: GPU DDK - OOB write in UntwiddlePOTSquare64bpp

- Also known as: EUVD-2026-113490, GHSA-X7M2-2J9Q-H4J6
- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Published: 2026-10-30 · Updated: 2026-10-30

## Summary

The affected software is the GPU graphics driver's user-space shared library used by the GPU GLES render process, which handles WebGPU content from web pages. A specially crafted web page can cause this library to read or write memory out of bounds, crashing the process, and on certain platforms, when that process runs with system privileges, this could enable further attacks on the device.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Imagination Technologies Graphics DDK: from 25.1 RTM2, through 25.3 RTM

## Description

A web page that contains unusual WebGPU content loaded into the GPU GLES render process can trigger a OOB read and/or write crash in the GPU GLES user-space shared library. On certain platforms, when the process executing graphics workload has system privileges this could enable further exploits on the device.
