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.
The rhev-hypervisor6 package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine hypervisor. It includes everything necessary to run and manage virtual machines: A subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent. Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions. A flaw was found in the way the Linux kernel's KVM hypervisor implementation emulated the syscall instruction for 32-bit guests. An unprivileged guest user could trigger this flaw to crash the guest.
