Description

In BIG-IP versions 15.1.0-15.1.0.4, 15.0.0-15.0.1.3, 14.1.0-14.1.2.3, 13.1.0-13.1.3.3, 12.1.0-12.1.5.1, and 11.6.1-11.6.5.1, the Traffic Management Microkernel (TMM) may stop responding when processing Stream Control Transmission Protocol (SCTP) traffic when traffic volume is high. This vulnerability affects TMM by way of a virtual server configured with an SCTP profile.
