  "details" : [ "The KVM subsystem in the Linux kernel through 4.13.3 allows guest OS users to cause a denial of service (assertion failure, and hypervisor hang or crash) via an out-of bounds guest_irq value, related to arch/x86/kvm/vmx.c and virt/kvm/eventfd.c.", "A reachable assertion failure flaw was found in the Linux kernel built with KVM virtualisation(CONFIG_KVM) support with Virtual Function I/O feature (CONFIG_VFIO) enabled. This failure could occur if a malicious guest device sent a virtual interrupt (guest IRQ) with a larger (>1024) index value." ],
  "statement" : "This issue does not affect the versions of the kernel package as shipped with Red Hat Enterprise Linux 5, 6 and Red Hat Enterprise MRG 2.\nThis issue affects the version of Linux kernel as shipped with Red Hat Enterprise Linux 7.
