The __netlink_deliver_tap_skb function in net/netlink/af_netlink.c in the
Linux kernel through 4.14.4, when CONFIG_NLMON is enabled, does not
restrict observations of Netlink messages to a single net namespace, which
allows local users to obtain sensitive information by leveraging the
CAP_NET_ADMIN capability to sniff an nlmon interface for all Netlink
activity on the system.
