CVE-2016-10229 in 4.4.x series

[Steven Pease]

Hi,

This is my first post - not currently subscribed so please CC me. :) I
searched a bit for this question, but couldn't find an answer (Googled
'2016-10229 site:lkml.org').

Does CVE-2016-10229 affect the newest version of the 4.4.x kernel
series (currently 4.4.68) and are there any plans to fix this in the
4.4 kernel series?

Thanks,

This one was fixed by upstream commit 197c949 ("udp: properly support
MSG_PEEK with truncated buffers"), which was backported in 4.4 as
commit dfe2042d96 in 4.4.21. So in short, 4.4.68 is safe.

Is there any particular reason that the CVE appears to be filed
against 4.4.60? Or is this just a mistake?

I have no idea why. Maybe they mentionned the current version at the
moment the CVE was issued (which seems to match). In fact this bug was
discovered as being a vulnerability long after the bug was fixed.
