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 Iris Xe MAX graphics hardware is presentOpen Device Manager, expand 'Display adapters', and look for 'Intel Iris Xe MAX' or 'Intel Iris Xe MAX Dedicated Graphics' in the list. Alternatively, run 'dxdiag' in the search bar and check the Display tab for the device name.Affected if The device 'Intel Iris Xe MAX' or 'Intel Iris Xe MAX Dedicated Graphics' appears in the display adapters list.
-
Find the installed driver version for Intel Iris Xe MAXIn Device Manager, right-click on the Intel Iris Xe MAX device, select 'Properties', go to the 'Driver' tab, and note the Driver Version field. Alternatively, in the same location click 'Driver Details' to see the specific driver files and their versions.Affected if A driver version number is displayed for the Intel Iris Xe MAX device.
-
Compare the installed version against the vulnerable rangeTake the driver version from step 2 (for example, 27.20.100.9466) and compare it numerically to 27.20.100.9466. Versions earlier than 27.20.100.9466 are affected; version 27.20.100.9466 and later are fixed.Affected if The installed driver version is a lower number than 27.20.100.9466 (for example, 27.20.100.9312 or 26.20.100.x.x would be affected).
If the Intel Iris Xe MAX dedicated graphics driver is installed and its version is less than 27.20.100.9466, the system is affected by this local privilege escalation vulnerability.
