Descriptions

arch/x86/kvm/emulate.c in the KVM subsystem in the Linux kernel through 3.17.2 does not properly perform RIP changes, which allows guest OS users to cause a denial of service (guest OS crash) via a crafted application.

arch/x86/kvm/emulate.c en el subsistema KVM en el kernel de Linux hasta 3.17.2 no realiza debidamente los cambios RIP, lo que permite a usuarios del sistema operativo invitado causar una denegación de servicio (caída del sistema operativo invitado) a través de una aplicación manipulada.

A flaw was found in the way the Linux kernel's KVM subsystem handled non-canonical addresses when emulating instructions that change the RIP (for example, branches or calls). A guest user with access to an I/O or MMIO region could use this flaw to crash the guest.
