Official Description

Buffer overflow in net/sctp/sm_statefuns.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel before 2.6.28-git8 allows remote attackers to have an unknown impact via an FWD-TSN (aka FORWARD-TSN) chunk with a large stream ID.

Source: NIST NVD / MITRE CVE Database

Attack Vector Analysis — CITED Relevance

The vulnerability is triggered by an FWD-TSN chunk with a large stream ID, which causes a buffer overflow in the net/sctp/sm_statefuns.c file. This can be exploited by sending a malicious FWD-TSN chunk to a vulnerable system over the network.
