The detection code will most likely come after the fix is applied.

In that case the 'ID' of the message could also be the commit ID of 
the fix in question:

	detect_exploit("[exploit for d8af4ce490e9: Fix syscall bug]")

or so - no CVE needed, it's a free form ID that can contain anything 
descriptive about the bug the attacker attempted to exploit.

Thanks,
