CVE-2020-12368
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 · uneditedInteger overflow in some Intel(R) Graphics Drivers before version 26.20.100.8141 may allow a privileged user to potentially enable an escalation of privilege 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 integer overflow vulnerability exists in Intel Graphics Drivers before version 26.20.100.8141. The flaw allows a privileged local user to potentially escalate privileges by exploiting the overflow condition in the graphics driver.

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.
-
Check if Intel Graphics Drivers are installedOpen Device Manager, expand 'Display adapters' and look for Intel graphics devices (e.g., Intel UHD Graphics, Intel Iris Xe, etc.). Alternatively, check Programs and Features for Intel Graphics software.Affected if No Intel Graphics device or driver software is present in the system.
-
Determine installed Intel Graphics Driver versionRight-click the Intel graphics device in Device Manager, select Properties, go to the Driver tab, and note the Driver Version field. Alternatively, run 'dxdiag' command and check the Display tab for driver version information.Affected if Unable to locate Intel Graphics Driver version information.
-
Compare installed version against affected rangeCompare the installed driver version number to 26.20.100.8141. If the installed version is lower (e.g., 26.20.100.7219, 26.20.100.6890, etc.), the system is potentially affected.Affected if Installed version is less than 26.20.100.8141.
-
Verify driver is actively loaded and in useCheck that the Intel Graphics Driver is not disabled. In Device Manager, ensure the Intel GPU does not show a disabled icon (arrow pointing down). The driver must be loaded for the vulnerability to be exploitable.Affected if Intel Graphics Driver is present but disabled or not loaded.
The system is affected if Intel Graphics Drivers are installed, loaded, and the version is 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. Prioritize systems where privileged users have local access.
