The netfilter subsystem in the Linux kernel through 4.15.7 mishandles the case of a rule blob that contains a jump but lacks a user-defined chain, which allows local users to cause a denial of service (NULL pointer dereference) by leveraging the CAP_NET_RAW or CAP_NET_ADMIN capability, related to arpt_do_table in net/ipv4/netfilter/arp_tables.c, ipt_do_table in net/ipv4/netfilter/ip_tables.c, and ip6t_do_table in net/ipv6/netfilter/ip6_tables.c.

CVE-2018-1065 kernel: netfilter: xtables NULL pointer dereference in ip6_tables.c:ip6t_do_table() leading to a crash
The Linux kernel at version 4.15.0-rc9 is vulnerable to a NULL pointer dereference ip6_tables.c:ip6t_do_table() leading to a crash. This vulnerability is only present under certain malformed iptables rulesets.
Inserting malformed rules its a privileged operation as root or a user with CAP_NET_RAW,CAP_NET_ADMIN capabilities ( see man setcap(8) ).
As this requires advanced privileges Red Hat Product Security has rated this flaw as moderate.
