InputMismatchException ao atualizar

Estou recebendo uma InputMismatchException depois de atualizar o cargo, está apontando para a linha 26 da minha classe CrudCargoService.

@Service
public class CrudCargoService {
    private final CargoRepository cargoRepository;
    private Boolean system = true;

    public CrudCargoService(CargoRepository cargoRepository) {
        this.cargoRepository = cargoRepository;
    }

    public void inicial(Scanner scanner) {
        while(system) {
            System.out.println("Qual ação deseja fazer?");
            System.out.println("0 - sair");
            System.out.println("1 - salvar");
            System.out.println("2 - atualizar");

            int action = scanner.nextInt();

            switch (action) {
            case 1:
                salvar(scanner);
                break;
            case 2:
                atualizar(scanner);
                break;
            default:
                system = false;
                break;
            }

        }

    }

    private void salvar(Scanner scanner) {
        System.out.println("Descrição do cargo:");
        String descricao = scanner.next();
        Cargo cargo = new Cargo();
        cargo.setDescricao(descricao);
        cargoRepository.save(cargo);
        System.out.println("Salvo");
    }

    private void atualizar(Scanner scanner) {
        System.out.println("Id:");
        int id = scanner.nextInt();
        System.out.println("Descrição do cargo:");
        String descricao = scanner.next();

        Cargo cargo = new Cargo();
        cargo.setId(id);
        cargo.setDescricao(descricao);
        cargoRepository.save(cargo);
        System.out.println("Atualizado");

    }
