The kvm_apic_has_events function in arch/x86/kvm/lapic.h in the Linux kernel through 4.1.3 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by leveraging /dev/kvm access for an ioctl call.

From the Ubuntu security team
