[ Upstream commit 80b78c39eb86e6b55f56363b709eb817527da5aa ]
The get->num_services variable is an unsigned int which is controlled by
the user. The struct_size() function ensures that the size calculation
does not overflow an unsigned long, however, we are saving the result to
an int so the calculation can overflow.
Both "len" and "get->num_services" come from the user. This check is
just a sanity check to help the user and ensure they are using the API
correctly. An integer overflow here is not a big deal. This has no
security impact.
Save the result from struct_size() type size_t to fix this integer
overflow bug.

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.
