Echo: linux: security update to 6.1.147-1

high Tenable Cloud Security Plugin ID 465070

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: bus: fsl-mc: fix double-free on mc_dev
 The blamed commit tried to simplify how the deallocations are done but, in the process, introduced a
 double-free on the mc_dev variable. In case the MC device is a DPRC, a new mc_bus is allocated and the
 mc_dev variable is just a reference to one of its fields. In this circumstance, on the error path only the
 mc_bus should be freed. This commit introduces back the following checkpatch warning which is a false-
 positive. WARNING: kfree(NULL) is safe and this check is probably not required + if (mc_bus) +
 kfree(mc_bus); (CVE-2025-38313)

Solution

Update the linux library and its related packages to version 6.1.147-1 or later.
