"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncomedi: me4000: Fix potential overrun of firmware buffer\n\n`me4000_xilinx_download()` loads the firmware that was requested by\n`request_firmware()`. It is possible for it to overrun the source\nbuffer because it blindly trusts the file format. It reads a data\nstream length from the first 4 bytes into variable `file_length` and\nreads the data stream contents of length `file_length` from offset 16\nonwards.\n\nAdd a test to ensure that the supplied firmware is long enough to\ncontain the header and the data stream. On failure, log an error and\nreturn `-EINVAL`.\n\nNote: The firmware loading was totally broken before commit ac584af59945\n(\"staging: comedi: me4000: fix firmware downloading\"), but that is the\nmost sensible target for this fix."
