How to fix?

Upgrade Centos:7 kernel-rt-trace-devel to version 0:3.10.0-229.14.1.rt56.141.13.el7_1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-trace-devel package and not the kernel-rt-trace-devel package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

The (1) udp_recvmsg and (2) udpv6_recvmsg functions in the Linux kernel before 4.0.6 do not properly consider yielding a processor, which allows remote attackers to cause a denial of service (system hang) via incorrect checksums within a UDP packet flood.
