  "description": "In the Linux kernel, the following vulnerability has been resolved:  comedi: me4000: Fix potential overrun of firmware buffer  \u0060me4000_xilinx_download()\u0060 loads the firmware that was requested by \u0060request_firmware()\u0060.  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 \u0060file_length\u0060 and reads the data stream contents of length \u0060file_length\u0060 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 \u0060-EINVAL\u0060.  Note: The firmware loading was totally broken before commit ac584af59945 (\u0022staging: comedi: me4000: fix firmware downloading\u0022), but that is the most sensible target for this fix.",
