CVE-2015-6496
conntrackd in conntrack-tools 1.4.2 and earlier does not ensure that the optional kernel modules are loaded before using them, which allows remote attackers to cause a denial of service (crash) via a (1) DCCP, (2) SCTP, or (3) ICMPv6 packet.

Does this matter?
Lower severity and a low EPSS score (3.20%). Track it; it rarely justifies an emergency change on its own.
