Section 4.3 says:

Finally, after all loss in the given window of segments
has been successfully retransmitted, cwnd MUST be set to no more than
ssthresh and congestion avoidance MUST be used to further increase
cwnd.

It should say:

Finally, after all loss in the given window of segments
has been successfully retransmitted, cwnd MUST be set to no less than
ssthresh and congestion avoidance MUST be used to further increase
cwnd.

Notes:

if set cwnd no more than ssthresh, it will using slow start algorithm instead of congestion avoidance algorithm. so it should say "cwnd no less than ..." instead of "cwnd no more than ...".
--VERIFIER NOTES--
This would be a significant design change in TCP. The original text is as intended by the community.
