Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

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. Identify installed browser
    Open the browser and navigate to chrome://version or check your package manager for installed Chrome/Chromium package
    Affected if Google Chrome or Chromium-based browser is installed
  2. Determine browser version
    Look for the version number in chrome://version page or run 'google-chrome --version' or 'chromium --version' in terminal
    Affected if Version is less than 75.0.3770.80
  3. Check OS distribution version
    Run 'cat /etc/os-release' or check your system documentation to identify the exact OS version
    Affected if Running Debian 10.0, Fedora 29 or 30, openSUSE Leap 15.0/15.1/42.3, or openSUSE Backports sle-15 with a vulnerable browser version

You are affected if you run Google Chrome or Chromium with a version below 75.0.3770.80 on any of the listed Linux distributions or as a standalone Chrome installation.
