struct atio7_fcp_cmnd is a variable-length data structure because of add_cdb_len, but it is embedded in struct atio_from_isp and copied around like a fixed-length data structure. For big CDBs > 16 bytes, get_datalen_for_atio() called on a fixed-length copy of the atio will access invalid memory. In some cases this can be fixed by moving the atio to the end of the data structure and using a variable-length allocation. In other cases such as allocating struct qla_tgt_cmd, the fixed-length data structures are preallocated for speed, so in the case that add_cdb_len != 0, allocate a separate buffer for the CDB. Also add memcpy_atio() as a safeguard against invalid memory accesses.

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 reStructuredText 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.
