CVE-2019-11156
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 · uneditedLogic errors in Intel(R) PROSet/Wireless WiFi Software before version 21.40 may allow an authenticated user to potentially enable escalation of privilege, denial of service, and 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 confidenceLogic errors in Intel(R) PROSet/Wireless WiFi Software before version 21.40 allow an authenticated user with local access to potentially escalate privileges, cause denial of service, or obtain information disclosure through the vulnerable wireless 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.
-
Verify Intel PROSet/Wireless WiFi Software is installedCheck Windows Programs and Features or registry for Intel PROSet/Wireless WiFi Software entry, or look for Intel wireless utility in installed programsAffected if The software is not listed or no Intel wireless utility is found on the system, the system is not affected by this specific product vulnerability
-
Identify installed Intel wireless software versionOpen the Intel PROSet/Wireless WiFi Software utility, typically accessible via system tray icon or Windows Start menu, and locate the version information in the About or Help section. Alternatively, check Add/Remove Programs for the version number displayed next to the Intel PROSet/Wireless entryAffected if The displayed version number is lower than 21.40 (for example, 21.30, 20.x, or earlier)
-
Confirm wireless driver component is presentOpen Device Manager, expand Network adapters, and verify an Intel wireless adapter with its driver is installed and enabled. Additionally, confirm the Intel PROSet wireless utility service is runningAffected if No Intel wireless adapter or driver is present and the Intel PROSet utility is not installed, the specific driver component affected by this CVE is not present
-
Verify local user access contextCheck whether standard user accounts exist on the system. This vulnerability requires an authenticated local user to exploit, so systems without additional local users (single-user home systems) have reduced attack surface, though the software flaw still exists if version is vulnerableAffected if The installed version is below 21.40 AND the system has multiple user accounts or allows local account access, making the privilege escalation vector applicable
The system is affected if Intel PROSet/Wireless WiFi Software is installed with a version lower than 21.40 and the Intel wireless driver component is present on the system.
