Summary

Hide ▲

Apple has introduced Memory Integrity Enforcement (MIE) in its new iPhone 17 and iPhone Air models. This security feature provides always-on memory safety protection across critical attack surfaces, including the kernel and over 70 userland processes. MIE is designed to prevent memory corruption exploits, particularly those used by mercenary spyware in targeted attacks. The technology leverages Enhanced Memory Tagging Extension (EMTE) and Tag Confidentiality Enforcement (TCE) to enhance memory safety and block common vulnerability classes such as buffer overflows and use-after-free bugs. The A19 and A19 Pro chips in these iPhone models are specifically designed to support MIE without sacrificing device performance. This development aims to make zero-day exploits more difficult by transforming MTE into a robust security feature.
