CVE-2018-1065
Published: 2 March 2018
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.
From the Ubuntu Security Team
It was discovered that the netfilter subsystem in the Linux kernel did not validate that rules containing jumps contained user-defined chains. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
