CVE-2015-5366

Published: 06 July 2015

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.

From the Ubuntu security team

A flaw was discovered in how the Linux kernel handles invalid UDP checksums. A remote attacker can cause a denial of service against applications that use epoll by injecting a single packet with an invalid checksum.
