Descriptions

Buffer overflow in the kvm_vcpu_ioctl_x86_setup_mce function in arch/x86/kvm/x86.c in the KVM subsystem in the Linux kernel before 2.6.32-rc7 allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a KVM_X86_SETUP_MCE IOCTL request that specifies a large number of Machine Check Exception (MCE) banks.

Desbordamiento de búfer en la función kvm_vcpu_ioctl_x86_setup_mce en arch/x86/kvm/x86.c en el subsistema KVM en el kernel de Linux anteriores a v2.6.32-rc7 permite a los usuarios locales causar una denegación de servicio (corrupción de memoria) o posiblemente obtener privilegios a través de una petición KVM_X86_SETUP_MCE IOCTL que especifica un elevado número de bancos de Machine Check Exception (MCE).
