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 checks

Work through these to decide whether this CVE applies to you.

  1. Check installed Chrome version via command line
    Run 'google-chrome --version' on Linux, 'chrome --version' on Windows, or open Chrome and navigate to chrome://settings/help to view the version
    Affected if The version shown is less than 143.0.7499.40 (for example, 143.0.7499.0, 142.0.xxxx.x, etc.)
  2. Confirm V8 JavaScript engine is in use
    V8 is the built-in JavaScript engine for Chrome and is always enabled by default. No manual check needed - this is a core component of every Chrome installation
    Affected if Chrome is running at all - V8 cannot be disabled in standard Chrome installations

A user is affected if their installed Google Chrome version is any version below 143.0.7499.40, since the V8 JavaScript engine vulnerability is always present in unpatched versions.
