# macOS: out-of-bounds read lets an app crash the system or read kernel memory

An out-of-bounds read in macOS allows a local app to trigger an unexpected system termination or read kernel memory. Apple fixed it with improved bounds checking in macOS Golden Gate 27.2.

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

## How to check

- Check the installed macOS version under Apple menu > About This Mac, or run `sw_vers -productVersion` in Terminal.
- Confirm whether the Mac is running a build older than macOS Golden Gate 27.2.

## Fix

- Update macOS to `27.2` (macOS Golden Gate) or later via System Settings > General > Software Update.
