Pointing to the stagefright bug, a forum member notes that, "finally got the update too. Did try the stagefright detector and .... still vulnerable, would be nice if someone use this vulnerability to root and PATCH the device."

If you haven't received the update notification yet, don't worry, as the forum members have shared the KDZ files using which you can manually install the update.
