CVE-2017-2596: Linux Kernel

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: up to and including 4.9.8
