  • Missing privilege level checks in x86 emulation of far 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).

  • Missing privilege level checks in x86 emulation of far 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).

  • Missing privilege level checks in x86 emulation of software interrupts (CVE-2014-7156).

  • Race condition in HVMOP_track_dirty_vram (CVE-2014-7154).
