CVE-2014-7842

Published: 29 November 2014

Race condition in arch/x86/kvm/x86.c in the Linux kernel before 3.17.4 allows guest OS users to cause a denial of service (guest OS crash) via a crafted application that performs an MMIO transaction or a PIO transaction to trigger a guest userspace emulation error report, a similar issue to CVE-2010-5313.

From the Ubuntu Security Team

A race condition with MMIO and PIO transactions in the KVM (Kernel Virtual Machine) subsystem of the Linux kernel was discovered. A guest OS user could exploit this flaw to cause a denial of service (guest OS crash) via a specially crafted application.
