Will Action/Func causes memory leak when stored as member reference inside another class?

Hi experts
I am passing a method into another class which stores this method as a member reference and Property method. Will these cause memory leak?

public class KeepReference
{
     private Action _callBackMethod1;
     public KeepReference(Action aMethod)
     {
          _callBackMethod1 = aMethod;
     }

     public Action CallBackMethod2 {get; set;}
}

public class CallingClass
{
      public void abc()
      {
                :
            KeepReference kkk = new KeepReference(CallBackMethod);  // memory leak?
                :
            kkk.CallBackMethod2 = CallBackMethod; // memory leak?

      }

      private void CallBackMethod()
      {...}
}

Thanks.

Not sure whether it is leaking memory.
But for normal delegates using "+=", the caller has to explicitly call "-=" in order to avoid memory leak. In my case, I use the delegate "Action" and that makes me ponder if I need to do similar thing in order to avoid memory leak.

What is your idea of a "memory leak?"

The memory leak that I am concerned about is that it is not released by garbage collector.
