NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-bootwrapper package and not the kernel-bootwrapper package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The sctp_process_param function in net/sctp/sm_make_chunk.c in the SCTP implementation in the Linux kernel before 3.17.4, when ASCONF is used, allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via a malformed INIT chunk.
