CVE-2026-22167— GPU DDK - Cache resident PM buffers writable by other GPU requestors, leading to arbitrary write to physical memory

Quick assessment

Affected
Imagination Technologies Graphics DDK
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Imagination Graphics DDK是英国Imagination公司的一款GPU驱动工具套件。 Imagination Graphics DDK存在缓冲区错误漏洞，该漏洞源于非特权用户运行的软件可能执行不当的GPU系统调用，强制GPU写入任意物理内存页，导致内核和驱动程序使用的内存页数据被破坏，从而改变其行为，并可能对受限的内部GPU缓冲区执行写操作，最终导致任意物理内存损坏。

Vulnerability Title
GPU DDK - Cache resident PM buffers writable by other GPU requestors, leading to arbitrary write to physical memory
Source: CVE Program / CVE List V5
Vulnerability Description
Software installed and run as a non-privileged user may conduct improper GPU system calls to force GPU to write to arbitrary physical memory pages. Under certain circumstances this exploit could be used to corrupt data pages not allocated by the GPU driver but memory pages in use by the kernel and drivers running on the platform altering their behaviour. This attack can lead the GPU to perform write operations on restricted internal GPU buffers that can lead to a second order affect of corrupted arbitrary physical memory.
