CVE-2017-17450 (opens in a new tab)How to fix?
There is no fixed version for Centos:6 kernel.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel package and not the kernel package as distributed by Centos.
See How to fix? for Centos:6 relevant fixed versions and status.
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.
