NVD Description

Note: Versions mentioned in the description apply only to the upstream python-perf package and not the python-perf package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

The prepare_vmcs02 function in arch/x86/kvm/vmx.c in the Linux kernel through 4.13.3 does not ensure that the "CR8-load exiting" and "CR8-store exiting" L0 vmcs02 controls exist in cases where L1 omits the "use TPR shadow" vmcs12 control, which allows KVM L2 guest OS users to obtain read and write access to the hardware CR8 register.
