commit74da779213upstream. The "cpool_populated" variable is the number of elements in the cpool[] array that have been populated. It is incremented in tcp_sigpool_alloc_ahash() every time we populate a new element. Unpopulated elements are NULL but if we have populated every element then this code will read one element beyond the end of the array.

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.
