https://notcve.org/view.php?id=CVE-2017-2596
06 Feb 2017 — The nested_vmx_check_vmptr function in arch/x86/kvm/vmx.c in the Linux kernel through 4.9.8 improperly emulates the VMXON instruction, which allows KVM L1 guest OS users to cause a denial of service (host OS memory consumption) by leveraging the mishandling of page references. La función nested_vmx_check_vmptr en arch/x86/kvm/vmx.c en el kernel de Linux hasta la versión 4.9.8 emula indebidamente la instrucción VMXON, lo que permite a usuarios del SO invitado KVM L1 provocar una denegación de servicio (consu... • http://www.debian.org/security/2017/dsa-3791 • CWE-772: Missing Release of Resource after Effective Lifetime •
