# macOS: use-after-free lets an app crash the system or corrupt kernel memory

A use-after-free flaw in macOS lets a local app trigger an unexpected system termination or corrupt kernel memory. The sources do not give a CVSS score or say whether it is exploited.

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

## How to check

- Check the installed macOS version with `sw_vers -productVersion` and compare it with the fixed releases.
- unknown for other checks; the sources do not name a specific setting or file.

## Fix

- Update macOS to `27.2` (Golden Gate), `15.8.2` (Sequoia), or `26.7.2` (Tahoe), depending on the installed major release.
