"A lack of proper input checks in the ICMPv6 processing in the SCTP
stack can lead to either a failed kernel assertion or to a NULL
pointer dereference. In either case, a kernel panic will follow.
Impact : A remote, unauthenticated attacker can reliably trigger a
kernel panic in a vulnerable system running IPv6. Any kernel compiled
with both IPv6 and SCTP support is vulnerable. There is no requirement
to have an SCTP socket open.

IPv4 ICMP processing is not impacted by this vulnerability."
