CVE-2020-12372
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 · uneditedUnchecked return value in some Intel(R) Graphics Drivers before version 26.20.100.8141 may allow a privileged user to potentially enable a 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 confidenceAn unchecked return value vulnerability in Intel Graphics Drivers before version 26.20.100.8141 allows a privileged user to potentially cause a denial of service via local access. The vulnerability stems from the driver failing to properly validate return values from certain function calls, which could lead to a denial-of-service condition.

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 on WindowsOpen Device Manager, expand 'Display adapters', right-click on Intel GPU entry and select 'Properties', go to the 'Driver' tab and note the driver version shown.Affected if The driver version displayed is lower than 26.20.100.8141 (e.g., 26.20.100.xxxx where xxxx is less than 8141, or any 10.x-25.x version).
-
Check Intel Graphics Driver via System InformationRun 'dxdiag' from the Run dialog, navigate to the 'Display' tab, and note the driver version listed under the Intel GPU name.Affected if The driver version shown is < 26.20.100.8141.
-
Check Intel Graphics Driver via Registry (Windows)Open Registry Editor, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}, look for the 'DriverVersion' value in the right pane.Affected if The DriverVersion string value is less than 26.20.100.8141.
-
Identify Intel Graphics Driver on LinuxRun 'lspci -v | grep -A 10 VGA' or check /proc/driver/nvidia/version (note: Intel GPU info may appear in dmesg or through 'intel_gpu_top' if installed).Affected if The Intel driver version displayed is earlier than 26.20.100.8141.
Your system is affected if Intel Graphics Drivers are installed with a version number lower than 26.20.100.8141.

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 data26.20.100.8141
Update Intel Graphics Drivers to version 26.20.100.8141 or later. Since this requires local access and a privileged user, ensure least-privilege principles and monitor for anomalous driver behavior.
