Ahead of the launch of iOS 16.2, which is expected to arrive next month, Apple has released a small iOS 16.1.1 and iPadOS 16.1.1 with bug fixes and security updates. It is recommended for all iOS 16 devices.
While the released notes are vague, the fix likely patches two nagging issues. One affected some users’ ability to stay connected to Wi-Fi networks and the other impacted Apple’s SKAdNetwork, which “lets advertisers measure the success of advertisements by attributing app installations to specific ad campaigns.”
There are also two security updates included in the release, neither of which has been exploited in the wild:

- 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
- Impact: A remote user may be able to cause unexpected app termination or arbitrary code execution
- Description: An integer overflow was addressed through improved input validation.
