What happens if a driver tries to KeSetEvent on a handle that is -no longer valid.

I am about to create an interface between an application DLL and a kernel
driver. The Application/DLL will create a synchronization event and pass the
handle to the kernel driver allowing it to Signal the event. My concern is
if for some reason the application crashes, and said event occurs, what
happens if the event handle is no longer valid? Any suggestions on
protection?
