CVE-2017-1000252

Published: 26 September 2017

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.

From the Ubuntu Security Team

It was discovered that the KVM subsystem in the Linux kernel did not properly bound guest IRQs. A local attacker in a guest VM could use this to cause a denial of service (host system crash).
