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 checks

Work through these to decide whether this CVE applies to you.

  1. Check Windows version and build number
    Open Command Prompt or PowerShell and run 'winver' or 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"'. Alternatively, run 'ver' in cmd to get the build number.
    Affected if The installed version is less than the affected build numbers: 17763.6659 (Win10 1809/Server 2019), 19044.5247 (Win10 21h2), 19045.5247 (Win10 22h2), 22621.4602 (Win11 22h2), 22631.4602 (Win11 23h2), 26100.2605 (Win11 24h2), 25398.1308 (Server 2022 23h2)
  2. Verify WwanSvc service status
    Open Services (services.msc) or run 'Get-Service WwanSvc' in PowerShell. Check if the service exists and its current status (Running/Stopped).
    Affected if The WwanSvc service is present and set to Running or Automatic start; the vulnerability only applies when this service is enabled
  3. Confirm patch installation status
    Run 'Get-HotFix | Where-Object {$_.HotFixID -like "KB*"} | Sort-Object InstalledOn -Descending | Select-Object -First 10' in PowerShell to list recently installed updates. Check for November 2024 or later Windows security updates.
    Affected if No recent security updates from November 2024 or later are installed, indicating the system may be unpatched

The system is affected if it runs a vulnerable Windows version listed above AND has the WwanSvc service enabled, and lacks the November 2024 security updates that address this vulnerability.
