(CVE-2015-4692) A flaw was discovered in how the Linux kernel handles invalid UDP checksums. A remote attacker could exploit this flaw to cause a denial of service using a flood of UDP packets with invalid checksums. (CVE-2015-5364) 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. (CVE-2015-5366)
