I/O port access privilege escalation in x86-64 Linux

ISSUE DESCRIPTION IRET and POPF do not modify EFLAGS.IOPL when executed by code at a privilege level other than zero. Since PV Xen guests run at privilege level 3 for 64-bit ones; 32-bit ones run at privilege level 1, to compensate for this the context switching of EFLAGS.IOPL requires the guest ...
