CWE-20  (opens in a new tab)

How to fix?

Upgrade RHEL:7 perf to version 0:3.10.0-327.36.1.el7 or higher.
This issue was patched in RHSA-2016:1847.

NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The netfilter subsystem in the Linux kernel through 4.5.2 does not validate certain offset fields, which allows local users to gain privileges or cause a denial of service (heap memory corruption) via an IPT_SO_SET_REPLACE setsockopt call.
