CVE-2026-22167
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSoftware 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA vulnerability in GPU drivers allows non-privileged users to make improper GPU system calls that force the GPU to write to arbitrary physical memory pages. This can corrupt kernel and driver memory pages, leading to a second-order effect where the GPU writes to restricted internal GPU buffers, corrupting arbitrary physical memory.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Imagination Technologies GPU driver is presentCheck system for installed Imagination Technologies GPU drivers/DDK. On Linux, look for modules like 'powervr' or check /sys/module/ for PVR (PowerVR) driver files. On embedded systems, check /dev for GPU device nodes and review loaded kernel modules with 'lsmod'.Affected if The system has Imagination Technologies (Imaginationtech) GPU drivers installed
-
Determine the installed Imagination DDK versionQuery the driver version through available interfaces. On Linux systems with PVR driver, check /sys/class/drm/card*/device/version or use 'modinfo' on the GPU kernel module. For embedded platforms, check /proc driver info files or use vendor-provided query tools.Affected if The installed version is <= 25.2 or exactly 25.3
-
Verify if unprivileged users have access to GPU accelerationCheck permissions on GPU device nodes (e.g., /dev/dri/*, /dev/mali*, /dev/pvr*) using 'ls -la'. Review GPU driver configuration files for access control settings. Check if user-space GPU libraries are world-readable and executable.Affected if Non-privileged users can access GPU device nodes or GPU acceleration features without restriction
A user is affected if their system has Imaginationtech DDK version 25.3 or earlier AND unprivileged users have direct access to GPU acceleration features.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-supplied GPU driver patches or updates; until patched, consider restricting unprivileged user access to GPU acceleration features or implementing additional memory protection mechanisms.
