CVE-2016-9588
arch/x86/kvm/vmx.c in the Linux kernel through 4.9 mismanages the #BP and #OF exceptions, which allows guest OS users to cause a denial of service (guest OS crash) by declining to handle an exception thrown by an L2 guest.
Does this matter?
Lower severity and a low EPSS score (0.43%). Track it; it rarely justifies an emergency change on its own.
