Red Hat Security Advisory 2016-1225-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: Two flaws were found in the way the Linux kernel's networking implementation handled UDP packets with incorrect checksum values. A remote attacker could potentially use these flaws to trigger an infinite loop in the kernel, resulting in a denial of service on the system, or cause a denial of service in applications using the edge triggered epoll functionality.

Red Hat Security Advisory 2016-0045-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Two flaws were found in the way the Linux kernel's networking implementation handled UDP packets with incorrect checksum values. A remote attacker could potentially use these flaws to trigger an infinite loop in the kernel, resulting in a denial of service on the system, or cause a denial of service in applications using the edge triggered epoll functionality. All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

Red Hat Security Advisory 2015-1788-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the kernel's implementation of the Berkeley Packet Filter. A local attacker could craft BPF code to crash the system by creating a situation in which the JIT compiler would fail to correctly optimize the JIT image on the last pass. This would lead to the CPU executing instructions that were not part of the JIT code. Two flaws were found in the way the Linux kernel's networking implementation handled UDP packets with incorrect checksum values. A remote attacker could potentially use these flaws to trigger an infinite loop in the kernel, resulting in a denial of service on the system, or cause a denial of service in applications using the edge triggered epoll functionality.

Two flaws were found in the way the Linux kernel's networking implementation handled UDP packets with incorrect checksum values. A remote attacker could potentially use these flaws to trigger an infinite loop in the kernel, resulting in a denial of service on the system, or cause a denial of service in applications using the edge triggered epoll functionality. A flaw was found in the way the Linux kernel's ext4 file system handled the "page size > block size" condition when the fallocate zero range functionality was used. A local attacker could use this flaw to crash the system.

Ubuntu Security Notice 2714-1 - Marcelo Ricardo Leitner discovered a race condition in the Linux kernel's SCTP address configuration lists when using Address Configuration Change (ASCONF) options on a socket. An unprivileged local user could exploit this flaw to cause a denial of service (system crash). 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. Various other issues were also addressed.
