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 Google Chrome browser on the system. On Windows, look for Chrome in Program Files or Program Files (x86). On macOS, check /Applications for Google Chrome.app. On Linux, check common package locations or run which google-chrome.
    Affected if Google Chrome is not installed on the system, so this CVE does not apply.
  2. Determine installed Chrome version
    Open Google Chrome, click the three-dot menu (top right), select Help, then About Google Chrome. The version number will be displayed on that page. Alternatively, navigate to chrome://settings/help in the browser address bar.
    Affected if Unable to determine the installed version.
  3. Compare version against affected range
    Note the full version number displayed (for example, 76.0.3809.87). Compare it numerically to the fixed version 76.0.3809.100.
    Affected if The installed version is earlier than 76.0.3809.100 (for example, 76.0.3809.87 or any version in the 75.x branch or earlier).

A user is affected if Google Chrome is installed and the version is lower than 76.0.3809.100.
