The dump command for reading a region passes a requested read length specified in words (4-byte units). The response overwrites the same field with the actual number of bytes read. The mailbox handler for DUMP which reads VPD data (region 23) is treating the response field as if it were still a word_cnt, thus multiplying it by 4 to set the read's "length". Given the read value was calculated based on the size of the read buffer, the longer response length runs off the end of the buffer. Fix by reworking the code to use the response field as a byte count.

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.
