Adopt Memory Integrity Enforcement and Pointer Authentication

Apple releases Memory Integrity Enforcement using hardware memory tagging to neutralize memory corruption exploits

“Use the default system allocator with no wrappers, no caches, or even custom implementations.”

Apple's WWDC session details Memory Integrity Enforcement, a security feature using ARM Memory Tagging Extensions (MTE) to prevent memory corruption exploits by enforcing type-aware allocation at the hardware level. The primary recommendation is to use Apple's default system allocator, which was rewritten over three years to optimize for this security model. While foundational to secure AI inference runtimes on Apple Silicon, this is a low-level systems security talk with limited direct AI industry signal.
