CVE-2020-12369
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 · uneditedOut of bound write in some Intel(R) Graphics Drivers before version 26.20.100.8336 may allow a privileged user to potentially enable 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 · moderate confidenceAn out-of-bounds write vulnerability in Intel Graphics Drivers before version 26.20.100.8336 allows a privileged local user to potentially write to memory outside intended bounds, which could be exploited for privilege escalation. The vulnerability stems from improper bounds checking in the graphics driver component.

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 Intel Graphics Drivers are installedOn Windows, open Device Manager and expand 'Display adapters' to see if an Intel graphics device is listed. On Linux, run 'lspci | grep -i vga' to check for Intel graphics hardware.Affected if An Intel graphics adapter is present in the system
-
Determine the installed Intel Graphics Driver version on WindowsOpen Device Manager, right-click the Intel graphics device, select 'Properties', go to the 'Driver' tab, and note the driver version displayed.Affected if The driver version shown is lower than 26.20.100.8336
-
Determine the installed Intel Graphics Driver version using Intel Driver & Support AssistantRun Intel Driver & Support Assistant (or similar Intel diagnostic tool) to scan for installed graphics drivers and report the exact version number.Affected if The reported version is lower than 26.20.100.8336
-
Check if the graphics driver is loaded and activeOn Windows, verify the driver is loaded by checking that the Intel graphics device shows as 'This device is working properly' in Device Manager. On Linux, check 'lsmod | grep i915' to see if the Intel i915 kernel module is loaded.Affected if The driver is loaded and the version is below 26.20.100.8336
A system is affected if it has Intel Graphics Drivers installed with a version number lower than 26.20.100.8336, and the driver is loaded or active.
