dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Windows build numberRun 'winver' or 'systeminfo' in Command Prompt, or use PowerShell: Get-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion' | Select-Object CurrentBuild, DisplayVersion, UBRAffected if The build number is lower than the threshold for your Windows release (10.0.10240.21034 for 1507, 10.0.14393.8148 for 1607, 10.0.17763.7434 for 1809, 10.0.19044.5965 for 21h2, 10.0.19045.5965 for 22h2, 10.0.22621.5472 for Win11 22h2, 10.0.22631.5472 for Win11 23h2, 10.0.26100.4270 for Win11 24h2)
-
Identify Windows release versionRun 'winver' to determine if you are on Windows 10 1507, 1607, 1809, 21h2, 22h2 or Windows 11 22h2, 23h2, 24h2Affected if Your specific Windows release version falls within the affected version ranges and the build number is below the corresponding patch threshold
-
Confirm Storage Management Provider presenceCheck for the Storage Management Provider service via PowerShell: Get-Service -Name 'StorSvc' or check for the feature in Windows Features. The provider is implemented as part of the Windows Storage subsystem.Affected if The StorSvc service exists and is running on the system, indicating the vulnerable component is present
You are affected if your Windows build number is lower than the patch threshold for your specific Windows release and the Windows Storage Management Provider component is present on your system.
