CVE-2014-0155

Published: 14 April 2014

The ioapic_deliver function in virt/kvm/ioapic.c in the Linux kernel through 3.14.1 does not properly validate the kvm_irq_delivery_to_apic return value, which allows guest OS users to cause a denial of service (host OS crash) via a crafted entry in the redirection table of an I/O APIC. NOTE: the affected code was moved to the ioapic_service function before the vulnerability was announced.

From the Ubuntu security team

A flaw was discovered in the Linux kernel virtual machine's (kvm) validation of interrupt requests (irq). A guest OS user could exploit this flaw to cause a denial of service (host OS crash).
