The following errata report has been verified for RFC9260,
"Stream Control Transmission Protocol". 

--------------------------------------
You may review the report below and at:
https://www.rfc-editor.org/errata/eid7148

--------------------------------------
Status: Verified
Type: Technical

Reported by: Michael Tüxen <tuexen@fh-muenster.de>
Date Reported: 2022-10-06
Verified by: Martin Duke (IESG)

Section: 3.3.3

Original Text
-------------
A receiver of an INIT ACK chunk with the a_rwnd value set to a
value smaller than 1500 MUST discard the packet, SHOULD send a
packet in response containing an ABORT chunk and using the
Initiate Tag as the Verification Tag, and MUST NOT change the
state of any existing association.


Corrected Text
--------------
If an endpoint in the COOKIE-WAIT state receives an INIT ACK chunk
with the a_rwnd value set to a value smaller than 1500, it MUST
destroy the TCB and SHOULD send an ABORT chunk.  If such an
INIT ACK chunk is received in any state other than CLOSED or
COOKIE-WAIT, it SHOULD be discarded silently (see Section 5.2.3).


Notes
-----
The handling of a_rwnd < 1500 should be similar to the handling of OS = 0 or MIS = 0.
