SACK out of window segments?

There had been a long thread on netfilter-devel recently with the subject
[PATCH] TCP window tracking patch backported from the 2.6 tree:
It seems that at least Linux 2.4.25 accepts and (S)ACKs segments which
otherwise looks to be out of window ones. In order to cope with that I had
to add code to the TCP connection tracking part of netfilter.
The question is wether that was a SACK bug in 2.4.25? Or there's something
in the RFCs we overlook and what looks like a violation is actually an RFC
Thank you your help,
