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 Remote Desktop allows an unauthorized attacker to execute code 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 use-after-free vulnerability in Windows Remote Desktop allows an unauthorized local attacker to execute arbitrary code. The vulnerability stems from improper memory management in the Remote Desktop component, where memory is accessed after being freed, leading to potential code execution.

MitigationApply the relevant Microsoft security patch for this vulnerability. Until the patch is available, restrict Remote Desktop access to trusted users and monitor for indicators of compromise.

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. Identify Windows Server version
    Run 'winver' from command prompt, or use 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"', or query registry: reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion" /v CurrentBuild
    Affected if The displayed version falls within or below these affected ranges: Server 2012 R2 (any), Server 2016 <= 10.0.14393.8519, Server 2019 < 10.0.17763.7919, Server 2022 < 10.0.20348.4294, Server 2022 23h2 < 10.0.25398.1913, Server 2025 <= 10.0.26100.6899
  2. Verify Remote Desktop is enabled
    Check registry key: reg query "HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server" /v fDenyTSConnections - value 0 means enabled, 1 means disabled. Or check via System Properties (right-click This PC > Properties > Remote settings)
    Affected if The fDenyTSConnections value is 0 (Remote Desktop is enabled)
  3. Confirm Remote Desktop service status
    Open Services console (services.msc) and check 'Remote Desktop Services' service status, or run: sc query TermService
    Affected if The Remote Desktop service (TermService) is running

You are affected if your Windows Server version is within the affected ranges listed AND Remote Desktop is enabled and running on your system.

  1. Open Windows Update on the affected server
  2. Check for and install the latest Windows security updates
  3. Verify the Remote Desktop services have been updated to the fixed versions
  4. Restart the server if prompted by the update installation
Caveat Standard Windows update risks apply; test updates in staging environment before production deployment
