Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

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 in the Chrome browser, or run 'Google Chrome --version' from command lineAffected if Version number displayed is less than 146.0.7680.153
-
Confirm V8 engine is in useThe V8 engine is the default JavaScript engine in Chrome; no configuration needed - this is the default stateAffected if Using Google Chrome as the browser (V8 is always enabled by default)
-
Verify Chrome is not receiving enterprise updatesCheck if Chrome is managed by enterprise policies via chrome://policy, or check if auto-updates are disabled in organizational management toolsAffected if Chrome is managed but policy blocks updates to version 146.0.7680.153 or later
User is affected if running any Google Chrome version below 146.0.7680.153 and can browse the web (enabling V8 JavaScript execution).
