Apple released iOS 11.4.1 earlier today. While today’s release brought an important security feature to iOS users in the shape of USB Restricted Mode [here’s how to use it], it is otherwise a smaller update. But like many other smaller updates, today’s release has also focused heavily on bug fixes and security improvements.

iOS 11.4.1 is now available for all the compatible iPhone, iPad, and iPod models bringing an improved Find My AirPod feature along with some stability and security fixes. Apple has fixed some critical security flaws with today’s release, including the ability of malicious apps to read restricted memory and gain elevated privileges.
