    branches (CVE-2014-8595).

  - Missing privilege level checks in x86 HLT, LGDT, LIDT,
    and LMSW emulation (CVE-2014-7155).

  - Hypervisor heap contents leaked to guests
    (CVE-2014-4021).

    branches (CVE-2014-8595).

  - Insufficient restrictions on certain MMU update
    hypercalls (CVE-2014-8594).

  - Intel VT-d Interrupt Remapping engines can be evaded by
    native NMI interrupts (CVE-2013-3495).
