[ Upstream commit41959c4f97] The curr pointer has advanced 14 bytes in jpeg_parse_app14_data. 1. jpeg_get_word_be(stream), it goes forward 2 bytes. 2. jpeg_skip(stream, 11), it goes forward 11 bytes. 3. jpeg_get_byte(stream), it goes forward 1 bytes. so the remain bytes of this segment should be (lp - 2 - 11 - 1), but not (lp - 2 - 11). if driver skip 1 extra bytes, the following parsing may go wrong.

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.
