In Symfony 4, the usage of the UserPasswordEncoderInterface is recommended in Controllers. Simply add a UserPasswordEncoderInterface as a parameter to the function in which you want to check the password and then add the code below.

public function changePasswordAction($old, $new, UserPasswordEncoderInterface $enc) {
   // Fetch logged in user object, can also be done differently.
   $auth_checker = $this->get('security.authorization_checker');
   $token = $this->get('security.token_storage')->getToken();
   $user = $token->getUser();

   // Check for valid password
   $valid = $encoder->isPasswordValid($user, $old);

   // Do something, e.g. change the Password
   if($valid)
      $user->setPassword($encoder->encodePassword($user, $new));
}
