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. (CVE-2015-5364)
Impact
An unprivileged user could use this flaw to cause a denial of service (DoS) to a remote system by way of specially crafted UDP packets.
