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

An out-of-bounds read in macOS could let a local app cause the system to terminate unexpectedly or read kernel memory. Apple fixed it with improved bounds checking in macOS Golden Gate 27.2, Sequoia 15.8.2 and 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` on each Mac and compare against the fixed versions.
- unknown for anything beyond the version check; the sources do not give a more specific check.

## Fix

- Update macOS to `27.2` (Golden Gate), `15.8.2` (Sequoia) or `26.7.2` (Tahoe) or later, via System Settings > General > Software Update.
