Apple has issued iOS 16.3 along with 13 reasons to update your iPhone now. That’s because iOS 16.3 fixes 13 security issues, some of which are serious.
Apple doesn’t give much detail about what’s fixed in iOS 16.3 to give time for as many people to update their iPhones as possible. This makes it less likely that attackers can get hold of the details.
Among the issues fixed in iOS 16.3 are three in WebKit—the engine that powers Apple’s Safari browser—and three in the Kernel at the heart of the iOS operating system, according to Apple’s support page. Thankfully, none of the issues fixed in iOS 16.3 have been used in real-life attacks.
