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.
-
Identify Windows version and build numberRun 'winver' from the Run dialog or execute 'systeminfo' in Command Prompt. Record the OS name, version, and build number shown.Affected if The detected Windows version matches any of the following: Windows 10 (any version including 20h2, 21h1, 21h2, 1607, 1809), Windows 11 (any version), Windows 7 (any version), Windows 8.1 (any version), Windows Rt 8.1 (any version), Windows Server 2008 (any version including R2), Windows Server 2012
-
Verify Windows Graphics Component is in useConfirm the system has a graphics subsystem by checking that display drivers are loaded. In PowerShell, run 'Get-WmiObject Win32_VideoController' to list video controllers. Alternatively, verify the system has a desktop environment.Affected if The Windows Graphics Component is present and operational, which is true for virtually all Windows desktop and server installations with display capabilities.
-
Check installed security updates for CVE-2022-34728Open Command Prompt or PowerShell and run 'wmic qfe list' or 'Get-HotFix | Sort-Object InstalledOn' to list installed updates. Look for a security update installed around September 2022 or later that corresponds to CVE-2022-34728. The update is typically listed as a Security Update for Windows.Affected if No security update addressing CVE-2022-34728 is installed, or the installed updates predate the September 2022 security patch release for this vulnerability.
