CVE-2014-0049

Published: 11 March 2014

Buffer overflow in the complete_emulated_mmio function in arch/x86/kvm/x86.c in the Linux kernel before 3.13.6 allows guest OS users to execute arbitrary code on the host OS by leveraging a loop that triggers an invalid memory copy affecting certain cancel_work_item data.

From the Ubuntu security team

A flaw was discovered in the Kernel Virtual Machine (KVM) subsystem of the Linux kernel. A guest OS user could exploit this flaw to execute arbitrary code on the host OS.
