# Apple iOS and macOS: out-of-bounds read lets a crafted file crash or leak memory

An out-of-bounds read in Apple's operating systems can be triggered by processing a maliciously crafted file. The result is a denial of service or disclosure of memory contents.

_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, visionOS) or `sw_vers` on macOS
- Compare against the fixed builds listed in the advisory: 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, 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 visionOS to 27.2
