Currently, rmi_f11_attention() and rmi_f12_attention() functions update the attn_data data pointer and size based on the size of the expected size of the attention data. However, if the actual valid data in the attn buffer is less then the expected value then the updated data pointer will point to memory beyond the end of the attn buffer. Using the calculated valid_bytes instead will prevent this from happening.

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.
