[ Upstream commita9f07790a4] This function may copy the pad0 field of struct hl_info_sec_attest to user mode which has not been initialized, resulting in leakage of kernel heap data to user mode. To prevent this, use kzalloc() to allocate and zero out the buffer, which can also eliminate other uninitialized holes, if any.

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.
