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

An out-of-bounds read in macOS lets a local app cause unexpected system termination or read kernel memory. Apple fixed it by removing the vulnerable code in macOS Golden Gate 27.2 and macOS Tahoe 26.7.2.

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

## How to check

- Run `sw_vers -productVersion` and compare it with `27.2` (Golden Gate) or `26.7.2` (Tahoe)
- unknown for other checks; the sources do not say

## Fix

- Update macOS to `27.2` (Golden Gate) or `26.7.2` (Tahoe) or later
