It is possible for it to overrun the source buffer because it blindly trusts the file format. It reads a data stream length from the first 4 bytes into variable `file_length` and reads the data stream contents of length `file_length` from offset 16 onwards.</p> <p>Add a test to ensure that the supplied firmware is long enough to contain the header and the data stream. On failure, log an error and return `-EINVAL`.</p> <p>Note: The firmware loading was totally broken before commit ac584af59945 (&#34;staging: comedi: me4000: fix firmware downloading&#34;), but that is the most sensible target for this fix.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>comedi: me4000: Fix potential overrun of firmware buffer</p> <p>`me4000_xilinx_download()` loads the firmware that was requested by `request_firmware()`.
