After you run the procedure your cursor is open. You can fetch it right away and use it like you would use a regular cursor.
SQL> set serveroutput on
SQL> CREATE OR REPLACE PACKAGE type_pack AS
  2  type t_cur is ref cursor;
  3  type t_tab is table of number;
  4  END type_pack;
  5  /
Package created.
SQL> CREATE OR REPLACE procedure test_ref(cur_output out sys_refcursor) i
  2  begin
  3    open cur_output for
  4    with test as
  5      (select 1 num from dual
  6       union select 2 num from dual
  7       union select 3 num from dual)
  8      select num
  9        from test;
10  end;
11  /
Procedure created.
SQL> CREATE OR REPLACE procedure run_test is
  2    cur_test sys_refcursor;
  3    tab_cur type_pack.t_tab;
  4  begin
  5    dbms_output.put_line('running...');
  6    test_ref(cur_test);
  7    fetch cur_test bulk collect
  8      into tab_cur;
  9    for i in 1 .. tab_cur.count
10    loop
11    dbms_output.put_line(tab_cur(i));
12    end loop;
13  end;
