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 · unedited
Use after free in Windows Universal Plug and Play (UPnP) Device Host allows an authorized attacker to elevate privileges locally.

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 · low confidence

Use-after-free vulnerability in Windows Universal Plug and Play (UPnP) Device Host enables a local authorized attacker to escalate privileges to higher integrity levels.

MitigationApply Microsoft security updates for Windows UPnP Device Host once released; restrict local access to trusted users to reduce attack surface.

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. Identify Windows version and build number
    Run 'winver' or 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"' to obtain the full Windows version and build number
    Affected if The build number falls below any of the following thresholds: 14393.9060, 17763.8644, 19044.7184, 19045.7184, 22631.6936, 26100.8246, 26200.8246, or 28000.1836 depending on your Windows release
  2. Verify UPnP Device Host component is present
    Check for the presence of the UPnP Device Host service by running 'sc query UPNPHOST' or inspecting 'C:\Windows\System32\upnphost.dll'
    Affected if The UPnP Device Host service or binary exists on the system, indicating the vulnerable component is installed
  3. Confirm UPnP Device Host service status
    Run 'sc queryex type= service state= all' and search for 'upnphost' or check the service via Services.msc
    Affected if The UPnP Device Host service is present in the services list, regardless of running state, as the vulnerability exists in the component itself
  4. Compare installed build against CVE version thresholds
    Obtain the exact build number via 'winver' or 'reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion" /v CurrentBuild' and cross-reference with the vulnerable version ranges listed in the CVE
    Affected if Your installed build number is lower than the fixed version for your specific Windows release as enumerated in the CVE affected products list

You are affected if your Windows build number is below the threshold for your specific Windows release AND the UPnP Device Host component exists on your system.

Windows 10 1607: 10.0.14393.9060 | Windows 10 1809: 10.0.17763.8644 | Windows 10 21h2: 10.0.19044.7184 | Windows 10 22h2: 10.0.19045.7184 | Windows 11 23h2: 10.0.22631.6936 | Windows 11 24h2: 10.0.26100.8246 | Windows 11 25h2: 10.0.26200.8246 | Windows 11 26h1: 10.0.28000.1836

  1. Identify your current Windows version and build number by running 'winver' or 'systeminfo' in Command Prompt
  2. Determine which Windows version category you are on (10 1607, 10 1809, 10 21h2, 10 22h2, 11 23h2, 11 24h2, 11 25h2, or 11 26h1)
  3. Open Windows Update by going to Settings > Update & Security > Windows Update
  4. Click 'Check for updates' and install all available security updates
  5. Alternatively, manually download the appropriate cumulative update from the Microsoft Update Catalog: https://www.catalog.update.microsoft.com/
  6. After installation, restart your computer to apply the security patch
  7. Verify the installed build number matches or exceeds the fixed version for your Windows release
Caveat Standard Windows cumulative update apply; may require restart; no major functional changes expected for this security-only update
