# Apple iOS and macOS: crafted file can crash an app via out-of-bounds read

An out-of-bounds read in Apple's operating systems lets a maliciously crafted file cause an app to terminate unexpectedly. The sources describe a crash, not code execution or data theft.

_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 (or `sw_vers -productVersion` on macOS) against the fixed versions listed in the fix field.

## 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`.
