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
Concurrent execution using shared resource with improper synchronization ('race condition') in Windows SSDP Service 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 · moderate confidence

A race condition exists in the Windows SSDP (Simple Service Discovery Protocol) Service where improper synchronization of shared resources allows an authorized attacker to manipulate timing and elevate privileges locally to a higher integrity level.

MitigationApply Microsoft security updates for this vulnerability when released. If the SSDP service is not required, consider disabling it to reduce attack surface.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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. Confirm the SSDP service exists on the system
    Run 'Get-Service -Name SSDPSRV' or 'sc query SSDPSRV' in PowerShell/Command Prompt to check if the Simple Service Discovery Protocol service is present.
    Affected if The service is present and enumerated in the service control manager.
  2. Retrieve the current Windows build version
    Run 'winver' or 'systeminfo | findstr /B /C:"OS Version"' to display the installed Windows version and build number.
    Affected if The build version falls below any of the following thresholds: 14393.9060 (Win10 1607), 17763.8644 (Win10 1809), 19044.7184 (Win10 21h2/22h2), 22631.6936 (Win11 23h2), 26100.8246 (Win11 24h2/25h2), or 28000.1836 (Win11 26h1).
  3. Check if the SSDP service is running
    Run 'Get-Service -Name SSDPSRV | Select-Object Status' or 'sc queryex SSDPSRV' to determine the current running state of the service.
    Affected if The service is in a running state, as the race condition vulnerability requires the SSDP service to be active for exploitation.
  4. Query the exact CurrentBuild and DisplayBuild in the registry
    Run 'reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion" /v CurrentBuild' and 'reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion" /v DisplayBuild' to obtain precise build numbers for comparison.
    Affected if The combined build number (CurrentBuild.DisplayBuild) is lower than the affected version thresholds listed in the CVE.

A system is affected if it runs a Windows version with a build number lower than the thresholds AND has the SSDP service available and running, as the race condition only triggers when the service is active.

Interim mitigation

Apply Microsoft security updates for this vulnerability when released. If the SSDP service is not required, consider disabling it to reduce attack surface.

Recommended fix High confidence

Apply the Microsoft security update for CVE-2026-32082, which raises the build to 10.0.14393.9060 (Win10 1607), 10.0.17763.8644 (Win10 1809), 10.0.19044.7184 (Win10 21h2), 10.0.19045.7184 (Win10 22h2), 10.0.22631.6936 (Win11 23h2), 10.0.26100.8246 (Win11 24h2), 10.0.26200.8246 (Win11 25h2), or 10.0.

  1. Identify the current Windows version and build by running 'winver' or 'systeminfo' in Command Prompt
  2. Open Windows Settings and navigate to Windows Update, or run 'ms-settings:windowsupdate'
  3. Check for and install the latest Windows security updates that address this vulnerability
  4. After updating, verify the build number matches or exceeds the fixed version for your Windows release: 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
  5. Confirm the SSDP Service (UxSms) is properly updated by checking the file version of %SystemRoot%\System32\ssdpsrv.dll after reboot
Caveat Standard Windows security updates typically have minimal risk; however, verify compatibility with critical line-of-business applications before deployment in production environments
