__vmbus_open() and vmbus_teardown_gpadl() do not inizialite the memory for the vmbus_channel_open_channel and the vmbus_channel_gpadl_teardown objects they allocate respectively. These objects contain padding bytes and fields that are left uninitialized and that are later sent to the host, potentially leaking guest data. Zero initialize such fields to avoid leaking sensitive information to the host.

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.
