The day after Apple released its last round of operating system updates (see “Apple Releases macOS 12 Monterey with iOS 15.1, iPadOS 15.1, watchOS 8.1, tvOS 15.1, and HomePod Software 15.1,” 25 October 2021), the company also pushed out iOS 14.8.1 and iPadOS 14.8.1 with security updates for those devices remaining on iOS 14 and iPadOS 14.
The updates include fixes for 12 security vulnerabilities, many of which could allow an attacker to execute code on your device. Apple says one of the exploits has been used in the wild.
You can install the updates in Settings > General > Software Update. Due to the severity of some of the vulnerabilities, we recommend that you update soon.
