# Apple iOS and macOS: out-of-bounds read lets a USB device crash or read kernel memory

An out-of-bounds read in Apple's operating systems can be triggered by a malicious USB device, causing the system to terminate unexpectedly. The same flaw can let the device read kernel memory.

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

## How to check

- Check the installed version under Settings > General > About (iOS/iPadOS) or Apple menu > About This Mac (macOS)
- Compare against the fixed versions: `iOS 26.7.2`, `iPadOS 26.7.2`, `iOS 27.2`, `iPadOS 27.2`, `macOS Tahoe 26.7.2`, `macOS Sequoia 15.8.2`, `macOS Golden Gate 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`
