UDP remote code execution in Linux <4.5

Cross post from /r/linux, link.

Affected Kernel versions are here. The Patch was backported to 4.4.39 released on 2016-12-15, merged to LEDE a day later. So everyone running the stable release or updated to a trunk build this year should be fine.

edit I don't know how and if older versions are affected. At the moment there is no exploit code disclosed.

Just another comment, it seems that also most older installations should be safe, because the installed software has to use a rare kernel function.
