The version of F5 Networks BIG-IP installed on the remote host is prior to 15.1.8 / 16.1.4 / 17.1.0. It is, therefore, affected by a vulnerability as referenced in the K67416037 advisory.

    A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel     privilege escalation from the context of a network service or an unprivileged process. If     sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the     auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network     service privileges to escalate to root or from the context of an unprivileged user directly if a     BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket.
    (CVE-2021-23133)ImpactAn attacker may be able to exploit this vulnerability to disclosure sensitive     information, modify data, or cause a Denial of Service (DoS).

Tenable has extracted the preceding description block directly from the F5 Networks BIG-IP security advisory.

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