# Apple OS: out-of-bounds read lets an app crash the system

An out-of-bounds memory read in Apple's operating systems can be triggered by an app, causing unexpected system termination. The sources describe a denial-of-service impact only, with no code execution or data access stated.

_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) and compare it with the fixed versions.

## Fix
