Descriptions
The kvm_vm_ioctl_assign_device function in virt/kvm/assigned-dev.c in the KVM subsystem in the Linux kernel before 3.1.10 does not verify permission to access PCI configuration space and BAR resources, which allows host OS users to assign PCI devices and cause a denial of service (host OS crash) via a KVM_ASSIGN_PCI_DEVICE operation.
La función kvm_vm_ioctl_assign_device en virt/kvm/assigned-dev.c de los subsistemas KVM en los kernel Linux anteriores a v3.1.10 no verifica los permisos de acceso al espacio de configuración PCI y recursos BAR, permitiendo que usuarios del SO asignen dispositivos PCI y provoquen una denegación del servicio (parada del SO) mediante una operación KVM_ASSIGN_PCI_DEVICE.
