# Apple: out-of-bounds write in image processing crashes apps

A malicious image can trigger an out-of-bounds write in Apple's image handling, causing the app processing it to terminate unexpectedly. The description reports only app termination (a crash), not code execution or data access.

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

## How to check

- Check the OS version on iPhone, iPad or Mac under Settings > General > About (or `sw_vers -productVersion` on macOS) and compare with the fixed versions below.

## 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`.
