Apple adds Memory Integrity Enforcement to iPhone 17
🔒 Apple introduced Memory Integrity Enforcement (MIE) on the new iPhone 17 and iPhone Air, implemented in the A19 and A19 Pro chips to deliver always-on memory safety across the kernel and more than 70 userland processes. MIE combines secure memory allocators, an enhanced synchronous Memory Tagging system called EMTE, and Tag Confidentiality Enforcement (TCE) to detect and block buffer overflows and use-after-free bugs. Apple says the design preserves performance while hardening devices against targeted mercenary spyware and exploitation of memory-corruption vulnerabilities.
