CVE-2017-17449
Last modified
CVE-2017-17449 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.44% chance of exploitation in the next 30 days.
