Peter Schneider reported that a system would no longer boot after updating to 6.8.4. Peter bisected the issue and identified commitb5fc07a5fb("scsi: core: Consult supported VPD page list prior to fetching page") as being the culprit. Turns out the enclosure device in Peter's system reports a byteswapped page length for VPD page 0. It reports "02 00" as page length instead of "00 02". This causes us to attempt to access 516 bytes (page length + header) of information despite only 2 pages being present. Limit the page search scope to the size of our VPD buffer to guard against devices returning a larger page count than requested.

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 reStructuredText 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.
