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. Confirm Google Chrome is installed
    Check if Google Chrome browser is present on the system by looking for chrome.exe on Windows, Google Chrome.app on macOS, or the google-chrome package on Linux
    Affected if Google Chrome is not installed - this vulnerability only affects Google Chrome, not other browsers even if they use libavif
  2. Determine installed Chrome version
    Open Chrome and navigate to chrome://version, or go to Help > About Google Chrome, to retrieve the full version number
    Affected if Cannot determine version - verification cannot be completed
  3. Compare version to affected range
    Compare the installed version number to 120.0.6099.109 - any version prior to this (e.g., 119.x, 118.x, etc.) falls within the affected range
    Affected if Installed version is less than 120.0.6099.109

User is affected if Google Chrome is installed and the version is below 120.0.6099.109
