CVE-2017-17450 is a vulnerability of currently unknown severity. net/netfilter/xt_osf.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for add_callback and remove_callback operations, which allows local users to bypass intended access restrictions because the xt_osf_fingers data structure is shared across all net namespaces.. EPSS estimates a 0.39% chance of exploitation in the next 30 days.
