src_size and aad_size are defined as u32, so the following expressions are currently being evaluated using 32-bit arithmetic: bit_len = src_size * 8; ... bit_len = aad_size * 8; However, bit_len is used afterwards in a context that expects a valid 64-bit value (the lower and upper 32-bit words of bit_len are extracted and written to hw). In order to make sure the correct bit length is generated and the 32-bit multiplication does not wrap around, cast src_size and aad_size to u64.

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.
