# Apple iOS and macOS: out-of-bounds write lets an app corrupt kernel memory

An out-of-bounds write in Apple's operating systems can be triggered by an app, causing unexpected system termination or corruption of kernel memory. The sources do not say whether this leads to code execution.

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

## How to check

- Check the device version under Settings > General > About (iOS, iPadOS, tvOS, visionOS) or run `sw_vers` on macOS
- Compare against the fixed builds: iOS and iPadOS `26.7.2` or `27.2`, macOS Tahoe `26.7.2`, macOS Sequoia `15.8.2`, macOS Golden Gate `27.2`, tvOS and visionOS `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 and visionOS to `27.2`
