How to fix?

There is no fixed version for Centos:6 kernel-devel.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-devel package and not the kernel-devel package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

sfc: farch: fix TX queue lookup in TX event handling

We're starting from a TXQ label, not a TXQ type, so efx_channel_get_tx_queue() is inappropriate (and could return NULL, leading to panics).
