How to fix?

Upgrade RHEL:6 python-perf to version 0:2.6.32-504.12.2.el6 or higher.
This issue was patched in RHSA-2015:0674.

NVD Description

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

The InfiniBand (IB) implementation in the Linux kernel package before 2.6.32-504.12.2 on Red Hat Enterprise Linux (RHEL) 6 does not properly restrict use of User Verbs for registration of memory regions, which allows local users to access arbitrary physical memory locations, and consequently cause a denial of service (system crash) or gain privileges, by leveraging permissions on a uverbs device under /dev/infiniband/.
