Race Condition Affecting perf package, versions <0:3.10.0-123.6.3.el7

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.

Race condition in the mac80211 subsystem in the Linux kernel before 3.13.7 allows remote attackers to cause a denial of service (system crash) via network traffic that improperly interacts with the WLAN_STA_PS_STA state (aka power-save mode), related to sta_info.c and tx.c.
