In the Linux kernel, the following vulnerability has been resolved:
comedi: me4000: Fix potential overrun of firmware buffer
`me4000_xilinx_download()` loads the firmware that was requested by
`request_firmware()`. 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.
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`.
Note: The firmware loading was totally broken before commit ac584af59945
("staging: comedi: me4000: fix firmware downloading"), but that is the
most sensible target for this fix.
