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. Verify Google Chrome is installed
    Check for Chrome installation by looking for the executable at typical paths (e.g., C:\Program Files\Google\Chrome\Application\chrome.exe on Windows, /Applications/Google Chrome.app on macOS, or via 'which google-chrome' or 'which chrome' on Linux)
    Affected if Google Chrome is present on the system
  2. Determine the installed Chrome version
    Open Chrome and navigate to chrome://version, or run 'google-chrome --version' (Linux/macOS) or 'chrome --version' from command line. The version number is displayed in the first line.
    Affected if Unable to determine version - manually verify through Help > About Google Chrome menu option
  3. Compare version against affected range
    Compare your installed version number to the affected range: versions prior to 108.0.5359.94. The full version string typically appears as X.X.X.XXXX where the fourth segment is the build number.
    Affected if Installed version is less than 108.0.5359.94 (for example, 108.0.5359.71 or any version 107.x.x.x)
  4. Confirm the V8 JavaScript engine is in use
    This is a V8 engine vulnerability - Chrome uses V8 by default for JavaScript execution in all pages. No additional configuration check needed.
    Affected if Google Chrome is being used to render or execute any JavaScript content (standard browser behavior)

A user is affected if Google Chrome is installed and the detected version number is less than 108.0.5359.94.
