Last modified

CVE-2015-5366 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 6.25% chance of exploitation in the next 30 days.
