Apologies to the uninformed downvoters :(
TrustZone is an ARM thing, and the iPhone Secure Enclave is indeed built on TrustZone.
Apple do not use Qualcomm and this a Qualcomm-specific bug. But Apple do use their own modded TrustZone.

- willvarfar 10y agoApologies, I stand corrected. All I've ever heard is it being explained as Apple's implementation of TrustZone, which conceivably could be modded so far as to be put on a separate coprocessor.
