How to fix?
There is no fixed version for RHEL:7 kernel-bootwrapper.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-bootwrapper package and not the kernel-bootwrapper package as distributed by RHEL.
See How to fix? for RHEL: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.
