  "details": "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.",
