There is no fixed version for Centos:7 kernel-tools-libs.
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.
See How to fix? for Centos:7 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
sfc: farch: fix TX queue lookup in TX flush done handling
We're starting from a TXQ instance number ('qid'), not a TXQ type, so efx_get_tx_queue() is inappropriate (and could return NULL, leading to panics).
