# CVE-2026-65586: GPU DDK - Write UAF due to missing cleanup reference for abort command submitted via PVRSRVRGXKickTA3DKM

- Also known as: EUVD-2026-113478, GHSA-8PW8-G8HF-X6V7
- 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 driver development kit (DDK) used with graphics hardware, specifically its GPU command submission handling. A non-privileged local application could exploit a memory management flaw to free memory the GPU is still using, then replace it, potentially allowing reads or writes to arbitrary physical memory.

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

Software installed and run as a non-privileged user may conduct improper GPU system calls to free memory in still in use, replace with another allocation and cause arbitrary memory reads or writes to physical memory pages. A memory buffer managed by a CPU thread of control (driver) and accessed by a GPU thread of control (firmware) can be freed while in use. Software installed and run as a non-privileged user may replace that buffer with another and replace a shared resource (memory page address list) managed by the CPU thread of control (driver) leading to the GPU accessing memory not managed by the CPU thread of control (driver).
