Pretty simple. Just make your custom form type a service, depending on the security context:

use Symfony\Component\Security\Core\SecurityContext;

class UserType extends AbstractType
{

    private $securityContext;

    public function __construct(SecurityContext $securityContext)
    {
        $this->securityContext = $securityContext;
    }

    public function buildForm(FormBuilder $builder, array $options)
    {
        // Current logged user
        $user = $this->securityContext->getToken()->getUser();

        // Add fields to the builder
    }

    public function getDefaultOptions(array $options)
    {
        return array(
            'required'   => false,
            'data_class' => 'Acme\HelloBundle\Entity\User'
        );
    }

    public function getName()
    {
        return 'user_type';
    }
}

Then mark the class as a service, with the special tag form.type:

services:
    form.type.user:
        class: Acme\HelloBundle\Form\Type\UserType
        arguments: ["@security.context"]
        tags:
            - { name: form.type, alias: user_type }

In your controller, instead of doing new UserType(), grap the service from the container:

$form = $this->createForm($this->get('form.type.user'), $data);
