CVE-2018-15318 is a vulnerability of currently unknown severity. In BIG-IP 14.0.0-14.0.0.2, 13.1.0.4-13.1.1.1, or 12.1.3.4-12.1.3.6, If an MPTCP connection receives an abort signal while the initial flow is not the primary flow, the initial flow will remain after the closing procedure is complete. TMM may restart and produce a core file as a result of this condition.. EPSS estimates a 1.34% chance of exploitation in the next 30 days.
