This kernel update provides an update to the 3.10 longterm branch, currently 3.10.28 and fixes the following security issues:

The ath9khtcsetbssidmask function in drivers/net/wireless/ath/ath9k/htcdrvmain.c in the Linux kernel through 3.12 uses a BSSID masking approach to determine the set of MAC addresses on which a Wi-Fi device is listening, which allows remote attackers to discover the original MAC address after spoofing by sending a series of packets to MAC addresses with certain bit manipulations. (CVE-2013-4579)

Pageexec reported a bug in the Linux kernel's recvmmsg syscall when called from code using the x32 ABI. An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or gain administrator privileges (CVE-2014-0038)

Faults during task-switch due to unhandled FPU-exceptions allow to kill processes at random on all affected kernels, resulting in local DOS in the end. One some architectures, privilege escalation under non-common circumstances is possible. (CVE-2014-1438)

The hamradio yamioctl() code fails to initialise the cmd field of the struct yamdrvioctl_cfg leading to a 4-byte info leak. (CVE-2014-1446)

Linux kernel built with the NetFilter Connection Tracking(NFCONNTRACK) support for IRC protocol(NFNAT_IRC), is vulnerable to an information leakage flaw. It could occur when communicating over direct client-to-client IRC connection(/dcc) via a NAT-ed network. Kernel attempts to mangle IRC TCP packet's content, wherein an uninitialised 'buffer' object is copied to a socket buffer and sent over to the other end of a connection. (CVE-2014-1690)
