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 Chrome version via command line
    Run `google-chrome --version` or `chrome --version` in terminal
    Affected if Version number is lower than 126.0.6478.54
  2. Check Chrome version via browser UI
    Open Chrome, click the three-dot menu, go to Help > About Google Chrome. The version is displayed on this page
    Affected if Displayed version is lower than 126.0.6478.54
  3. Check installed package version on Fedora
    Run `dnf list installed google-chrome-stable` or `rpm -q google-chrome-stable`
    Affected if Installed version is lower than 126.0.6478.54-1 or package is not present
