Yes, the SCTP_SENDALL handling code fixed by commit ba59fb027307 (currently
in net tree) was indeed introduced by commit 4910280503f3 ("sctp: add support
for snd flag SCTP_SENDALL process in sendmsg") in v4.17-rc1 which was not
backported into any of our older branches.

Therefore only master and stable branches are affected.

Comment 4 Michal Kubeček 2019-02-08 21:50:51 UTC

Commit ba59fb027307 ("sctp: walk the list of asoc safely") is in mainline now
so that it's going to be in v5.0-rc6.

Comment 5 Marcus Meissner 2019-02-14 13:07:16 UTC

was there any publishing of this issue?

Comment 6 Michal Kubeček 2019-02-18 07:26:15 UTC

Doesn't really matter anymore as the fix is in master (via 4.20-rc6) and stable
(via 4.20.8) branches and we don't need it anywhere else.

Reassigning to security team.

Should be "via 5.0-rc6".
