# Apple iOS and macOS: type confusion lets an app crash the system

A type confusion bug in Apple's operating systems was fixed with better memory handling. A malicious app can trigger it to force an unexpected system termination, which is a denial-of-service effect.

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

## How to check

- Check the device OS version in Settings > General > About (iOS, iPadOS, visionOS, watchOS, tvOS) or Apple menu > About This Mac (macOS)
- Compare against the fixed builds listed in the advisory: iOS 26.7.2, iPadOS 26.7.2, macOS Tahoe 26.7.2, macOS Sequoia 15.8.2, iOS/iPadOS/tvOS/visionOS/watchOS 27.2

## Fix

- Update iOS and iPadOS to `26.7.2` or `27.2`
- Update macOS Tahoe to `26.7.2`, macOS Sequoia to `15.8.2`, or macOS Golden Gate to `27.2`
- Update tvOS, visionOS and watchOS to `27.2`
