An out-of-bounds read in Apple's operating systems lets an app crash the device or read kernel memory. Apple fixed it with improved input validation in the listed iOS, iPadOS, macOS, tvOS, visionOS and watchOS releases.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the current version under Settings > General > About (iOS, iPadOS, visionOS, watchOS, tvOS) or Apple menu > About This Mac (macOS).
