kernel security update

CentOS Errata and Security Advisory CESA-2016:0045

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. (CVE-2015-5364, CVE-2015-5366, Important)

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.
