commit 003f01c780020daa9a06dea1db495b553a868c29 upstream.
The video buffer used by the queue is a vb2_v4l2_buffer, not a plain
vb2_buffer. Using the wrong type causes the allocation of the buffer
storage to be too small, causing a out of bounds write when
__init_vb2_v4l2_buffer initializes the buffer.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
