Descriptions

The kvm_emulate_hypercall function in arch/x86/kvm/x86.c in KVM in the Linux kernel 2.6.25-rc1, and other versions before 2.6.31, when running on x86 systems, does not prevent access to MMU hypercalls from ring 0, which allows local guest OS users to cause a denial of service (guest kernel crash) and read or write guest kernel memory via unspecified "random addresses."

La función kvm_emulate_hypercall en el archivo arch/x86/kvm/x86.c en KVM en el kernel de Linux versión 2.6.25-rc1 y otras versiones anteriores a 2.6.31, cuando se ejecuta en sistemas x86, no impide el acceso a hiperllamadas MMU desde el timbre 0, lo que permite a los usuarios del sistema operativo invitado local causar una denegación de servicio (bloqueo del kernel invitado) y leer o escribir la memoria del kernel invitado por medio de "random addresses” no especificadas.
