CVE-2017-17449

CVE-2017-17449 affects the Linux kernel: the __netlink_deliver_tap_skb function in net/netlink/af_netlink.c can allow local attackers with CAP_NET_ADMIN to sniff Netlink activity across all net namespaces when CONFIG_NLMON is enabled. This results in information disclosure (exposure of kernel Net...
