There is no fixed version for Centos:7 kernel-rt-trace.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-trace package and not the kernel-rt-trace 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:

i40e: Fix use-after-free in i40e_client_subtask()

Currently the call to i40e_client_del_instance frees the object pf->cinst, however pf->cinst->lan_info is being accessed after the free. Fix this by adding the missing return.

Addresses-Coverity: ("Read from pointer after free")
