CWE-399  (opens in a new tab)

How to fix?

Upgrade Amazon-Linux:2018.03 kernel-tools to version 0:3.14.48-33.39.amzn1 or higher.
This issue was patched in ALAS-2015-565.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-tools package and not the kernel-tools package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2018.03 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.
