CVE-2015-5366  (opens in a new tab)
CWE-835  (opens in a new tab)

How to fix?

Upgrade RHEL:6 perf to version 0:2.6.32-573.3.1.el6 or higher.
This issue was patched in RHSA-2015:1623.

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:6 relevant fixed versions and status.

The (1) udp_recvmsg and (2) udpv6_recvmsg functions in the Linux kernel before 4.0.6 provide inappropriate -EAGAIN return values, which allows remote attackers to cause a denial of service (EPOLLET epoll application read outage) via an incorrect checksum in a UDP packet, a different vulnerability than CVE-2015-5364.
