CVE-2017-2596 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.40% chance of exploitation in the next 30 days.
