dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Chrome versionNavigate to chrome://version in the Chrome browser or go to Chrome menu > Help > About Google Chrome to view the version numberAffected if The displayed version is less than 150.0.7871.115 (for example, 150.0.7871.0, 149.x.x.x, etc.)
