CVE-2019-11153
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 · uneditedMemory corruption issues in Intel(R) PROSet/Wireless WiFi Software extension DLL before version 21.40 may allow an authenticated user to potentially enable escalation of privilege, information disclosure and a denial of service 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.

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 installedOpen Control Panel > Programs and Features, or run 'appwiz.cpl', and look for entries containing 'Intel PROSet' or 'Intel Wireless' in the nameAffected if The software is not listed in installed programs - the vulnerability does not apply
-
Locate the installed version numberIn Programs and Features, find the Intel PROSet/Wireless WiFi entry and note the version number displayed in the 'Version' columnAffected if The displayed version is a version number less than 21.40 (for example, 21.30, 20.x, 19.x, etc.)
-
Alternative version check via Windows RegistryOpen Registry Editor (regedit) and navigate to 'HKLM\SOFTWARE\Intel\Wireless' or 'HKLM\SOFTWARE\WOW6432Node\Intel\Wireless' and look for a 'Version' or 'DriverVersion' string valueAffected if The registry version value is present and is less than 21.40
-
Confirm the extension DLL component existsCheck for the presence of Intel wireless utility files in the installation directory, typically under 'C:\Program Files\Intel\WiFi' or 'C:\Program Files (x86)\Intel\WiFi' - look for DLL files related to the PROSet wireless utilityAffected if The Intel wireless software files exist on the system, indicating the vulnerable component is present
-
Determine local access contextVerify that an authenticated local user account exists on the system - this vulnerability requires local access to exploitAffected if The system allows local user authentication (standard desktop/workstation configuration) and the software version is below 21.40
A user is affected if Intel PROSet/Wireless WiFi Software is installed with a version number less than 21.40, as versions prior to 21.40 contain the vulnerable memory corruption flaw in the extension DLL.
