How to fix?

Upgrade RHEL:7 kernel-rt-doc to version 0:3.10.0-229.14.1.rt56.141.13.el7_1 or higher.
This issue was patched in RHSA-2015:1788.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-doc package and not the kernel-rt-doc package as distributed by RHEL. See How to fix? for RHEL:7 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.
