16.0.1.1. It is, therefore, affected by a vulnerability as referenced in the K05300051 advisory.

  - On BIG-IP versions 16.0.x before 16.0.1.1, 15.1.x before 15.1.3, 14.1.x before 14.1.4, 13.1.x before
    13.1.3.6, and 12.1.x before 12.1.5.3, the Traffic Management Microkernel (TMM) may stop responding when
    processing Stream Control Transmission Protocol (SCTP) traffic under certain conditions. This
    vulnerability affects TMM by way of a virtual server configured with an SCTP profile. Note: Software
    versions which have reached End of Technical Support (EoTS) are not evaluated. (CVE-2021-23013)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
