CVE-2025-20031
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 · uneditedImproper input validation for some Intel(R) Graphics Drivers may allow an authenticated user to potentially enable denial of service via local access.
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 · high confidenceImproper input validation in Intel(R) Graphics Drivers allows an authenticated local user to potentially cause a denial of service. The vulnerability stems from the driver failing to properly validate input data, which could lead to a system crash or service disruption when exploited locally by an authenticated user.

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 Intel Graphics Driver installationOpen Device Manager (devmgmt.msc), expand 'Display adapters', and note if an Intel GPU is listed (e.g., Intel UHD Graphics, Intel Iris Xe, etc.)Affected if No Intel GPU is listed in Device Manager under Display adapters
-
Determine installed driver versionRight-click the Intel GPU in Device Manager, select 'Properties', go to the 'Driver' tab, and record the Driver Version and Driver Date fieldsAffected if Driver version cannot be determined or the driver is present but version is unknown
-
Verify driver is actively loadedOpen Task Manager, go to the 'Performance' tab, select the GPU section, and confirm the Intel GPU shows as active and in useAffected if The Intel GPU driver is installed but not loaded or not in use (may indicate different driver in use)
-
Check for authenticated local user access contextReview system to confirm whether untrusted or lower-privilege authenticated local users have access to the system. This vulnerability is exploitable by any authenticated local user.Affected if The system allows untrusted or lower-privilege authenticated local users to log in interactively
You are affected if an Intel Graphics Driver is installed and loaded, and the system permits authenticated local user access - compare your driver version to Intel's latest release to confirm vulnerability status since no specific version range is provided.

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 dataUpdate Intel Graphics Drivers to the latest version provided by Intel through their official driver download channels or Windows Update. Verify that the driver update is applied across all affected systems.
