"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncomedi: me_daq: Fix potential overrun of firmware buffer\n\n`me2600_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. Although it checks that the supplied firmware is at least 16\nbytes long, it does not check that it is long enough to contain the data\nstream.\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`."
