Description Adam Mariš 2017-04-26 15:23:53 UTC 
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.
