Echo: linux: security update to 6.1.170-1

high Tenable Cloud Security Plugin ID 461061

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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.
 (CVE-2026-31747)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
