commit ef6c8d6ccf0c1dccdda092ebe8782777cd7803c9 upstream.
When SCTP handles an INIT chunk, it calls for example:
sctp_sf_do_5_1B_init
sctp_verify_init
sctp_verify_param
sctp_process_init
sctp_process_param
handling of SCTP_PARAM_SET_PRIMARY
sctp_verify_init() wasn't doing proper size validation and neither the
later handling, allowing it to work over the chunk itself, possibly being
uninitialized memory.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
