CVE-2017-17448

Public on 2017-12-07
Modified on 2018-01-18
Description

The net/netfilter/nfnetlink_cthelper.c function in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for new, get, and del operations. This allows local users to bypass intended access restrictions because the nfnl_cthelper_list data structure is shared across all net namespaces.
