[PATCH net 0/2] sctp: validate INIT in COOKIE-ECHO when auth disabled

From: Xin Long <lucien.xin@gmail.com>
Date: 2026-06-16 00:34:21
Also in: linux-sctp

This series fixes a security gap in SCTP's COOKIE-ECHO handling when
cookie authentication is disabled.

Currently, INIT chunks embedded in cookies are not re-verified after
unpacking, creating a vulnerability when cookie_auth_enable=0. This
series first refactors error handling, then adds the missing validation.

Xin Long (2):
  sctp: factor out INIT verification failure handling
  sctp: add INIT verification after cookie unpacking
