The MITRE CVE dictionary describes this issue as:

The sctp_process_unk_param function in net/sctp/sm_make_chunk.c in the Linux kernel and earlier, when SCTP is enabled, allows remote attackers to cause a denial of service (system crash) via an SCTPChunkInit packet containing multiple invalid parameters that require a large amount of error data.

Red Hat is aware of this issue and is tracking it via the following bug:

This issue did not affect the version of Linux kernel as shipped with Red Hat Enterprise Linux 3 as it did not include support for SCTP. Future kernel updates in Red Hat Enterprise Linux 4, 5 and Red Hat Enterprise MRG may address this flaw.
