 - From: Jan Beulich Subject: x86emul: CMPXCHG8B ignores operand size prefix Otherwise besides mis-handling the instruction, the comparison failure case would result in uninitialized stack data being handed back to the guest in rDX:rAX (32 bits leaked for 32-bit guests, 96 bits for 64-bit ones). This is XSA-200.
