Subject: CVE request: -- Linux kernel: Null pointer dereference in
 tipc_nl_publ_dump

Hello,
Without checking the pointer to the netlink socket attribute, it could 
cause a null pointer dereference when parsing the nested attributes in 
function tipc_nl_publ_dump. It allows local users to cause a denial of 
service. This vulnerability affects Linux kernel versions from 3.19 to 4.6.
