Last modified

CVE-2017-8106 is a vulnerability of currently unknown severity. The handle_invept function in arch/x86/kvm/vmx.c in the Linux kernel 3.12 through 3.15 allows privileged KVM guest OS users to cause a denial of service (NULL pointer dereference and host OS crash) via a single-context INVEPT instruction with a NULL EPT pointer.. EPSS estimates a 0.33% chance of exploitation in the next 30 days.
