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 versionOpen Command Prompt and run 'winver' or 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"' to retrieve the installed Windows version and build numberAffected if The version falls below any of the following thresholds: Windows 10 1507 < 10.0.10240.21034, Windows 10 1607 < 10.0.14393.8148, Windows 10 1809 < 10.0.17763.7434, Windows 10 21h2 < 10.0.19044.5965, Windows 10 22h2 < 10.0.19045.5965, Windows 11 22h2 < 10.0.22621.5472, Windows 11 23h2 < 10.0.22631.547
-
Confirm Storage Management Provider is presentVerify the Windows Storage Management Provider component exists by checking for the storagewmi.mof file in the system (typically located at C:\Windows\System32\wbem\) or run 'Get-Command Storage*' in PowerShellAffected if The Storage Management Provider files are present on the system (this is the default state on affected Windows versions)
-
Verify vulnerability is exploitable locallyConfirm you have local administrator or authorized user access to the system where the check is being performed (the vulnerability requires a locally authorized attacker)Affected if The attacker has valid local credentials to log into the system
The system is affected if it runs any Windows 10 or Windows 11 version listed above with a build number below the specified threshold and the Storage Management Provider component is present (default state).
