Memory Corruption in Apple iOS and macOS

Executive Summary

This is a memory integrity vulnerability where an app could potentially alter copy-on-write memory pages unexpectedly. Copy-on-write is a memory optimization technique where memory pages are shared between processes until one tries to modify them, at which point a private copy is made. The issue allows an app to cause unintended changes to these shared memory pages.
