The Centos security team deemed this advisory irrelevant for Centos:7.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-tools-libs package and not the kernel-tools-libs package as distributed by Centos.
An integer overflow flaw was found in the Linux kernel. This issue leads to the kernel allocating skb_shared_info in the userspace, which is exploitable in systems without SMAP protection since skb_shared_info contains references to function pointers.
