CVE-2020-0503
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 access control in Intel(R) Graphics Drivers before version 26.20.100.7212 may allow an authenticated user to potentially enable information disclosure 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 · moderate confidenceImproper access control in Intel(R) Graphics Drivers before version 26.20.100.7212 allows an authenticated local user to potentially access sensitive information beyond their intended permissions. The vulnerability requires local access and an authenticated session, but does not require elevated privileges, enabling a low-privilege user to potentially read restricted data.

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.
-
Verify Intel Graphics Driver is installedOpen Device Manager (devmgmt.msc), expand Display adapters. Look for any Intel graphics device listed (e.g., Intel UHD Graphics, Intel Iris Xe, etc.).Affected if No Intel graphics adapter is found in Device Manager, then this CVE does not apply.
-
Locate the installed driver versionIn Device Manager, right-click the Intel graphics device, select Properties, go to the Driver tab. Note the Driver Version field.Affected if Unable to retrieve driver version information from Device Manager.
-
Compare the driver version against the vulnerable rangeTake the driver version shown (e.g., 26.20.100.7153) and compare it numerically to 26.20.100.7212. The first three numeric segments (26.20.100) must match; then check if the fourth segment is less than 7212.Affected if The installed version is less than 26.20.100.7212 (for example, 26.20.100.7153 or 25.20.100.6500).
-
Confirm local authenticated access is possibleVerify that local user accounts exist on the system and that the system allows local login. This vulnerability requires an authenticated local user session.Affected if The system does not permit local user authentication (e.g., remote-only access only).
You are affected if Intel Graphics Driver is installed with a version lower than 26.20.100.7212 and the system allows local authenticated user sessions.
