CVE-2017-2596

CVE-2017-2596 affects the Linux kernel’s KVM VMX handling. The nested_vmx_check_vmptr function in arch/x86/kvm/vmx.c through kernel 4.9.8 incorrectly emulates the VMXON instruction, enabling a local L1 guest user to cause host memory exhaustion and a denial of service by abusing mishandled page r...
