Created: May 12, 2026    Updated: May 14, 2026
Found In Version: 10.22.33.2
Severity: Standard
Applicable for: Wind River Linux LTS 22
Component/s: Kernel

Description

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`.
