Apple’s release notes mention that these updates feature bug fixes, however, it is unclear what they are as the company has not shared any details.

libxml2

Available for: iPhone 8 and later, iPad Pro (all models), iPad Air 3rd generation and later, iPad 5th generation and later, and iPad mini 5th generation and later

Although not mentioned in the release notes, it is also expected that this update fixes an iPhone bug that causes Wi-Fi to randomly disconnect.

Due to the nature of these security flaws, it is recommended that users update immediately. The updates can be installed by going to Settings > General > Software Update. Alternatively, you can also download the iOS 16.1.1 and iPadOS 16.1.1 ipsw firmware files to manually update your device or restore it.

Apple is currently beta testing iOS 16.2 and iPadOS 16.2, which will ship with a number of new features and changes in December. Check out our coverage of the changes below:
