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 checksWork through these to decide whether this CVE applies to you.
-
Check installed Google Chrome versionOpen Chrome, go to Menu > Help > About Google Chrome, or navigate to chrome://settings/help, or run 'google-chrome --version' from command lineAffected if Version is earlier than 93.0.4577.82 (e.g., 93.0.4577.80 or below)
-
Confirm Chrome is using the ANGLE graphics backendNavigate to chrome://gpu in the browser address bar and look for ' ANGLE ' in the Graphics Feature Status sectionAffected if ANGLE is listed as active or enabled in the GPU information
-
For Fedora users: identify Fedora release versionRun 'cat /etc/fedora-release' or 'rpm -q fedora-release' from the terminalAffected if The output shows Fedora 33 or Fedora 35 AND Chrome version is below 93.0.4577.82
You are affected if Google Chrome version is below 93.0.4577.82 (or if running Fedora 33/35 with an unpatched Chrome package).

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped93.0.4577.82
Update Google Chrome to version 93.0.4577.82 or later to remediate this vulnerability.
Chrome 93.0.4577.82 or later (or google-chrome-stable package version 93.0.4577.82-1 or later for Fedora)
- Update Google Chrome to version 93.0.4577.82 or later. On desktop, Chrome automatically checks for updates and installs them; manually trigger an update via chrome://settings/help or reinstall from google.com/chrome
- For Fedora systems, run 'sudo dnf update google-chrome-stable' or 'sudo dnf update' to apply the patched package for versions 33 and 35
- Verify the installed version by navigating to chrome://version and confirm the version number is 93.0.4577.82 or higher
- Restart Chrome completely (close all windows and reopen) to ensure the patched version is fully loaded
