Apple releases iOS 14.7.1 to fix Apple Watch unlock and zero-day exploit

iOS 14.7 was released last week, with features such as support for Apple’s magnetic battery pack. Unfortunately, the update is also interrupted the “Unlock with iPhone” feature that Apple Watch wearers used to easily access their wrist wear. Now an update is coming to fix that.

But even if you don’t have an Apple Watch, you’ll still need to install iOS 14.7.1 (and for Mac owners, macOS 11.5.1) as soon as possible, because safety notes from Apple reveal that the two updates it released today fix bugs that are already being exploited in the wild. The memory corruption issues in Apple’s desktop and mobile operating systems have been assigned the same vulnerability ID and attributed to an anonymous researcher.


Available for: iPhone 6s and later, iPad Pro (all models), iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, and iPod touch (7th generation)

Available for: macOS Big Sur

Impact: An application may be able to run arbitrary code with kernel privileges. Apple is aware of a report that this issue may have been actively exploited.

Description: A memory corruption issue was addressed through improved memory handling.
