# Apple macOS: crafted file can crash an app via out-of-bounds write

An out-of-bounds write in an unnamed macOS component lets a maliciously crafted file terminate the app that processes it. The sources describe only an unexpected app termination, not code execution.

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

## How to check

- Run `sw_vers -productVersion` and compare with the fixed releases: macOS Golden Gate `27.2`, macOS Sequoia `15.8.2`, macOS Tahoe `26.7.2`
- Check Software Update in System Settings for pending macOS updates

## Fix

- Update macOS to Golden Gate `27.2`, Sequoia `15.8.2`, or Tahoe `26.7.2`, whichever matches the installed major release
