CVE-2015-5364 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 6.27% chance of exploitation in the next 30 days.
