CVE-2017-12154

Priority
Medium
Description
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.
Ubuntu-Description
It was discovered that the nested KVM implementation in the Linux kernel in
some situations did not properly prevent second level guests from reading
and writing the hardware CR8 register. A local attacker in a guest could
use this to cause a denial of service (system crash).
