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 checksWork through these to decide whether this CVE applies to you.
-
Check Windows build numberRun 'winver' or 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"' to retrieve the installed Windows build version.Affected if The build number is lower than the fixed version for your Windows release (19044.5737 for 21h2, 19045.5737 for 22h2, 22621.5189 for 11 22h2, 22631.5189 for 11 23h2, 26100.3775 for 11 24h2/Server 2025, 20348.3453 for Server 2022, 25398.1551 for Server 2022 23h2).
-
Verify DWM Core Library versionLocate dwmcore.dll in System32 folder, right-click and view Properties, or run 'powershell (Get-Item C:\Windows\System32\dwmcore.dll).VersionInfo' to retrieve file version.Affected if The file version is lower than the patched version or the file shows no version info indicating it predates the security update.
-
Confirm DWM is runningOpen Task Manager, go to Details tab, look for dwm.exe process, or run 'tasklist | findstr dwm' in command prompt.Affected if DWM is running and the system is on an affected Windows version below the fixed builds.
-
Check for security update installationRun 'powershell Get-HotFix | Where-Object {$_.Description -eq "Security Update"} | Sort-Object InstalledOn -Descending | Select-Object -First 10' to list recent security updates, or check Windows Update history.Affected if No security update for CVE-2025-24062 (released April 2025) is listed in the installed updates.
A system is affected if it runs an unpatched Windows version within the affected build ranges and the CVE-2025-24062 security update has not been installed.
