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 installed Chrome versionNavigate to chrome://settings/help or use 'Help > About Google Chrome' in the menu to display the current version numberAffected if Version shown is less than 147.0.7727.101 (for example, 147.0.7727.100 or earlier)
-
