Stable kernels 4.8.13 and 4.4.37
Greg Kroah-Hartman has announced the release of the 4.8.13 and 4.4.37 stable kernels. As usual, there are fixes throughout the tree and users of those kernel series should upgrade.

Note that the fix for the kernel code execution vulnerability using AF_PACKET sockets (also known as CVE-2016-8655) has not made it into these stable kernels. Those running systemd may want to check Lennart Poettering's blog post on how to mitigate the problem for services started by systemd.
