commit 00a0eec59ddbb1ce966b19097d8a8d2f777e726a upstream. Index of rvring is computed using pointer arithmetic. However, since rvring->rvdev->vring is the base of the vring array, computation of rvring idx should be reversed. It previously lead to writing at negative indices in the resource table.

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.
