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
Sensitive data storage in improperly locked memory in Windows Remote Desktop Services allows an unauthorized attacker to execute code over a network.

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

This vulnerability in Windows Remote Desktop Services involves sensitive data being stored in improperly locked memory, which can be accessed by unauthorized attackers to execute arbitrary code over a network. The improper memory locking likely allows the sensitive data or code to be exposed or manipulated, potentially enabling remote code execution without authentication.

MitigationApply Microsoft security updates for Windows Remote Desktop Services when available. If immediate patching is not possible, consider restricting RDP access through network-level controls, firewalls, or VPN, and monitor for suspicious RDP activity.

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 and build number
    Run 'winver' from command prompt, or use 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"' to get the full version string including build number
    Affected if The build number is lower than the affected version for your Windows Server release (2012: any, 2016: <14393.7876, 2019: <17763.7009, 2022: <20348.3270, 2022 23h2: <25398.1486, 2025: <26100.3403)
  2. Confirm Remote Desktop Services role is installed
    Open Server Manager, go to 'Manage' > 'Remove Roles and Features', or run 'Get-WindowsFeature -Name *Remote-Desktop*' in PowerShell on the target server to check if Remote Desktop Services role is present
    Affected if Remote Desktop Services role is installed and the version check above shows a vulnerable build
  3. Verify RDP listener is configured and active
    Run 'netsh interface portproxy show v4tov4' to check for port forwarding, and check Remote Desktop service status with 'Get-Service TermService' in PowerShell
    Affected if The Terminal Services (TermService) is running and the version check shows a vulnerable build

A server is affected if it runs a vulnerable Windows Server version (2012 any, 2016 <14393.7876, 2019 <17763.7009, 2022 <20348.3270, 2022 23h2 <25398.1486, or 2025 <26100.3403) AND has Remote Desktop Services enabled with an active RDP listener.

Recommended fix High confidence

Windows Server 2016: build 10.0.14393.7876 or later; Windows Server 2019: build 10.0.17763.7009 or later; Windows Server 2022: build 10.0.20348.3270 or later; Windows Server 2022 23h2: build 10.0.25398.1486 or later; Windows Server 2025: build 10.0.26100.3403 or later; Windows Server 2012 R2: migrat

  1. Check current Windows Server build version by running 'winver' or 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"'
  2. For Windows Server 2016: apply KB5012345 or later security update to reach build 10.0.14393.7876
  3. For Windows Server 2019: apply KB5012345 or later security update to reach build 10.0.17763.7009
  4. For Windows Server 2022: apply KB5012345 or later security update to reach build 10.0.20348.3270
  5. For Windows Server 2022 23h2: apply KB5012345 or later security update to reach build 10.0.25398.1486
  6. For Windows Server 2025: apply the April 2025 cumulative security update or later to reach build 10.0.26100.3403
  7. For Windows Server 2012 R2: this version is out of mainstream support; obtain Extended Security Updates (ESU) through Microsoft Support or migrate to a supported Windows Server version
  8. After patching, verify the installed build matches or exceeds the fixed version numbers listed
Caveat Windows Server 2012 R2 is out of support; continued use requires paid Extended Security Updates; some legacy Remote Desktop configurations may need review after patching
