Echo: linux: security update to 6.1.147-1

medium Tenable Cloud Security Plugin ID 465445

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: net: ch9200: fix uninitialised access
 during mii_nway_restart In mii_nway_restart() the code attempts to call mii->mdio_read which is
 ch9200_mdio_read(). ch9200_mdio_read() utilises a local buffer called "buff", which is initialised with
 control_read(). However "buff" is conditionally initialised inside control_read(): if (err == size) {
 memcpy(data, buf, size); } If the condition of "err == size" is not met, then "buff" remains
 uninitialised. Once this happens the uninitialised "buff" is accessed and returned during
 ch9200_mdio_read(): return (buff[0] | buff[1] << 8); The problem stems from the fact that
 ch9200_mdio_read() ignores the return value of control_read(), leading to uinit-access of "buff". To fix
 this we should check the return value of control_read() and return early on error. (CVE-2025-38086)

Solution

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