This kernel-rt update provides an update to the 3.10 longterm branch, currently 3.10.24 and fixes the following security issues:

The ipv6createtempaddr function in net/ipv6/addrconf.c in the Linux kernel through 3.10 does not properly handle problems with the generation of IPv6 temporary addresses, which allows remote attackers to cause a denial of service (excessive retries and address-generation outage), and consequently obtain sensitive information, via ICMPv6 Router Advertisement (RA) messages. (CVE-2013-0343)
