dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Chrome versionNavigate to chrome://version in the Chrome address bar or run 'google-chrome --version' (Linux) or '"C:\Program Files\Google\Chrome\Application\chrome.exe" --version' (Windows) in a command promptAffected if The displayed version number is lower than 146.0.7680.177
-
Verify Chrome is the active browserCheck if Chrome browser process is currently running on the system via Task Manager (Windows) or Activity Monitor/Process Monitor (macOS/Linux)Affected if Chrome is actively running and the version from step 1 is in the affected range
-
Confirm Navigation component is presentThis is a core Chrome component - open chrome://navigation (if available) or inspect running Chrome processesAffected if Chrome is running with a vulnerable version from step 1 - the Navigation component exists in all standard Chrome installations
-
Check browser patch statusNavigate to chrome://settings/help to see if the browser reports it is up to date, or check if auto-updates are enabled in chrome://settingsAffected if The browser reports a version below 146.0.7680.177 or indicates updates are pending
You are affected if Chrome is actively used and the installed version is lower than 146.0.7680.177, as this version range contains the use-after-free vulnerability in the Navigation component.
