The patch fixes two kinds of bugs in DxeCore that accesses memory which might be freed or owned by other modules. The two bugs don't cause functionality issue. 1. CoreValidateHandle() checks whether the handle is valid by validating its signature. The proper way is to check whether the handle is in the handle database. 2. CoreDisconnectControllersUsingProtocolInterface() and CoreOpenProtocol() de-reference Link pointer which is already freed. The proper way is to not de-reference the pointer.
