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 Chrome versionNavigate to chrome://settings/help or go to Menu > Help > About Google Chrome to view the current version numberAffected if Version is earlier than 97.0.4692.99 (for example, 97.0.4692.71 or any prior version)
-
Review installed extensionsNavigate to chrome://extensions/ and examine all currently installed extensionsAffected if Any extension from an untrusted or unknown source is installed
-
Inspect extension permissionsIn chrome://extensions/, click on each extension and review its requested permissions, especially DevTools access, script injection, or host permissionsAffected if Extensions have broad permissions that could facilitate heap corruption when processing crafted HTML pages
Environment is affected if Chrome version is below 97.0.4692.99 AND any untrusted or high-permission extension is installed that could trigger the vulnerability when processing crafted HTML content.
