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 Google Chrome version
    Navigate to chrome://version in the Chrome browser or go to Settings > About Chrome to view the installed version number
    Affected if the installed version is earlier than 115.0.5790.170

Your environment is affected if Google Chrome is installed and its version is lower than 115.0.5790.170, since the type confusion vulnerability exists in the V8 JavaScript engine of all prior versions.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

AI-assisted, checked against the advisory. Informational, not a guarantee.

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.

Recommended fix High confidence

Chrome 115.0.5790.170 or later

  1. Verify current Chrome version by navigating to chrome://settings/help or Help > About Google Chrome
  2. Download Chrome 115.0.5790.170 or later from official channels (google.com/chrome or your system's package manager)
  3. Install the updated Chrome version
  4. Restart the browser to apply the update
  5. For Linux systems using package managers, run system updates: Fedora (dnf update), Gentoo (emerge --sync && emerge -av www-client/google-chrome or glsa-check -f all)
Caveat Chrome stable updates typically have minimal breaking changes; enterprise environments may need to verify extension compatibility
