"Downfall is characterized as a vulnerability due to a memory optimization feature that unintentionally reveals internal hardware registers to software. With Downfall, untrusted software can access data stored by other programs that typically should be off-limits: the AVX GATHER instruction can leak the contents of the internal vector register file during speculative execution."
