APIC fail: Intel ‘Sunny Cove’ chips with SGX spill secrets

A group of computer scientists has identified an architectural error in certain recent Intel CPUs that can be abused to expose SGX enclave data like private encryption keys.

They call it ÆPIC Leak because it affects the memory-mapped registers of the local Advanced Programmable Interrupt Controller (APIC), which helps the CPU handle interrupt requests from various sources in order to facilitate multiprocessing.
