A16-FuseBypass: Debug Logic Enabled on Production Apple Silicon
Overview
This repository documents a critical hardware-level vulnerability in the Apple A16 Bionic chip used in iPhone 14 Pro Max and related devices. The flaw allows debug logic—meant strictly for development silicon—to be executed on production-fused devices ( dev-fused = 0 ) running stock, unmodified iOS with debug = 0x0 .
No jailbreak. No provisioning profile. No tampering. Just flawed hardware trust enforcement.
Summary of Findings
Device: iPhone 14 Pro Max (Apple A16 Bionic)
Fuse State: dev-fused = 0 (production)
(production) Boot Args: debug = 0x0
Expected: Debug logic should be permanently disabled
Observed: SecureROM, firmware, HAL, and co-processors execute debug routines
