2017-10-26 Thread Euan Harris
decode_vmx_inst() does not read instruction operands correctly on VM exit: * It incorrectly uses vmx_inst_info's address_size field to calculate the sizes of the exit-causing instruction's operands. The sizes of the operands are specified in the SDM and might depend on whether the
