There is no fixed version for Centos:7 perf.
NVD Description
Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by Centos.
See How to fix? for Centos:7 relevant fixed versions and status.
The net_ctl_permissions function in net/sysctl_net.c in the Linux kernel before 3.11.5 does not properly determine uid and gid values, which allows local users to bypass intended /proc/sys/net restrictions via a crafted application.
