Guess what? #IBPB (the speculation barrier) was broken in microcode for return instructions on the latest Intel CPUs. Linux also used it wrongly for AMD CPUs, so we could revive #Inception!

HW defenses against Spectre are tricky: they need to be applied correctly by the SW, and we need to trust that the HW does what its supposed to. Our latest work "Breaking the Barrier" exploits loopholes in both of these issues on Intel and AMD parts. https://t.co/DBzOXdf75h
