The mld_input function in sys/netinet6/mld6.c in the kernel in NetBSD 4.0, FreeBSD, and KAME, when INET6 is enabled, allows remote attackers to cause a denial of service (divide-by-zero error and panic) via a malformed ICMPv6 Multicast Listener…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.43%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
