Details

The _netlinkdelivertapskb function in net/netlink/afnetlink.c in the Linux kernel through 4.14.4, when CONFIGNLMON 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 CAPNETADMIN capability to sniff an nlmon interface for all Netlink activity on the system.
