Descriptions
The em_syscall function in arch/x86/kvm/emulate.c in the KVM implementation in the Linux kernel before 3.2.14 does not properly handle the 0f05 (aka syscall) opcode, which allows guest OS users to cause a denial of service (guest OS crash) via a crafted application, as demonstrated by an NASM file.
La función em_syscall en arch/x86/kvm/emulate.c en la implementación KVM en el kernel de linux anterior a v.3.2.14 no maneja correctamente el opcode 0f05, permitiendo a los clientes usuarios del sistema operativo causar una denegación de servicio a través de una aplicación hecha a mano, como lo demuestra un archivo NASM.
