Ross Lagerwall d60f458e4c efi: cper: Fix possible out-of-bounds access 
[ Upstream commit 45b14a4ffc ]

When checking a generic status block, we iterate over all the generic
data blocks. The loop condition only checks that the start of the
generic data block is valid (within estatus->data_length) but not the
whole block. Because the size of data blocks (excluding error data) may
vary depending on the revision and the revision is contained within the
data block, ensure that enough of the current data block is valid before
dereferencing any members otherwise an out-of-bounds access may occur if
estatus->data_length is invalid.

This relies on the fact that struct acpi_hest_generic_data_v300 is a
superset of the earlier version.  Also rework the other checks to avoid
potential underflow.

README 

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
