Pardon MIE?

Apple's Memory Integrity Enforcement (MIE), a five-year security initiative combining hardware memory tagging, read-only kernel zones, and a privileged monitor, was bypassed by a small team in five days using two bugs and a clever technique. The vulnerability (CVE-2026-28952), an integer overflow in the trusted read-only zone writer, highlights that despite being the most serious kernel memory-safety system shipped in a consumer OS, MIE still has exploitable flaws. Memory bugs remain the root cause of approximately 70% of high-severity vulnerabilities across major software products, making hardware-level protections like MIE critical to preventing unauthorized access to sensitive device data.
