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 if Internet Explorer 11 is installedOpen Command Prompt and run: reg query 'HKLM\SOFTWARE\Microsoft\Internet Explorer' /v Version. Alternatively, open IE and navigate to About Internet Explorer in the Help menu.Affected if The version returned includes '11.' (e.g., 11.0.xxxx)
-
Check if Microsoft Edge is installedOpen Command Prompt and run: reg query 'HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\msedge.exe' or simply check if msedge.exe exists in C:\Program Files (x86)\Microsoft\Edge\Application\ or C:\Program Files\Microsoft\Edge\Application\Affected if Microsoft Edge is found on the system (all versions are affected)
-
Confirm browser is in useCheck if Internet Explorer or Edge browsers are accessible or installed on the system. Run: wmic product where "name like 'Internet Explorer%'" get name,versionAffected if Either IE 11 or Edge is installed and accessible on the system
If either Microsoft Internet Explorer version 11 or Microsoft Edge is present on the system, the environment is potentially affected since both browsers are fully affected by this memory corruption vulnerability.
