RHSA-2016:0045: Important: kernel security update

First published: Tue Jan 19 2016(Updated: )

The kernel packages contain the Linux kernel, the core of any Linux<br>operating system.<br><li> Two flaws were found in the way the Linux kernel's networking</li> implementation handled UDP packets with incorrect checksum values. A remote<br>attacker could potentially use these flaws to trigger an infinite loop in<br>the kernel, resulting in a denial of service on the system, or cause a<br>denial of service in applications using the edge triggered epoll<br>functionality. (CVE-2015-5364, CVE-2015-5366, Important)<br>All kernel users are advised to upgrade to these updated packages, which<br>contain backported patches to correct these issues. The system must be<br>rebooted for this update to take effect.<br>
