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 installation
    Run 'google-chrome --version' or check Help > About Google Chrome in the browser menu
    Affected if Chrome is not installed on the system
  2. Compare installed Chrome version to the patched version
    Check if the installed version number is less than 72.0.3626.81
    Affected if Installed version is 72.0.3626.80 or lower, or any version below 72.0.3626.81
  3. Check distribution package manager for Chrome version on Linux
    Run 'rpm -qa | grep -i chrome' on RHEL/Fedora or 'dpkg -l | grep -i chrome' on Debian to list installed Chrome packages and their versions
    Affected if The packaged version is less than 72.0.3626.81

User is affected if Google Chrome or Chromium is installed with a version lower than 72.0.3626.81
