In the Linux kernel, the following vulnerability has been resolved:
comedi: me_daq: Fix potential overrun of firmware buffer
me2600_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. Although it checks that the supplied firmware is at least 16
bytes long, it does not check that it is long enough to contain the data
stream.
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.

In the Linux kernel, the following vulnerability has been resolved: comedi: me_daq: Fix potential overrun of firmware buffer `me2600_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. Although it checks that the supplied firmware is at least 16 bytes long, it does not check that it is long enough to contain the data stream. 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`.
