-
Identify installed Chrome versionOpen Chrome and navigate to chrome://settings/help, or from command line run 'google-chrome --version' (Linux), check About Google Chrome in the menu (Mac), or check registry (Windows)Affected if The displayed version is lower than 84.0.4147.89
-
Confirm V8 JavaScript engine is in useThis is the default JavaScript engine in Chrome and cannot be disabled through user settings; no manual check requiredAffected if Chrome browser is actively used to render untrusted web content
-
Check for Chrome on Debian 10Run 'dpkg -l | grep google-chrome' or 'apt list --installed 2>/dev/null | grep google-chrome'Affected if Google Chrome package is installed and version is below 84.0.4147.89
-
Check for Chrome on Fedora 31 or 32Run 'rpm -qi google-chrome-stable' or 'dnf list installed google-chrome-stable'Affected if Google Chrome package is installed and version is below 84.0.4147.89
-
Check for Chrome on openSUSE Leap 15.1 or 15.2Run 'rpm -qi google-chrome-stable' or 'zypper se google-chrome-stable'Affected if Google Chrome package is installed and version is below 84.0.4147.89
