Echo: linux: security update to 6.1.170-1

high Tenable Cloud Security Plugin ID 457775

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: 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`. (CVE-2026-31748)

Solution

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