    CVE-2015-5366

    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.
