Echo: linux: security update to 6.1.140-1

medium Tenable Cloud Security Plugin ID 460367

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: firmware: arm_scmi: Balance device
 refcount when destroying devices Using device_find_child() to lookup the proper SCMI device to destroy
 causes an unbalance in device refcount, since device_find_child() calls an implicit get_device(): this, in
 turns, inhibits the call of the provided release methods upon devices destruction. As a consequence, one
 of the structures that is not freed properly upon destruction is the internal struct device_private dev->p
 populated by the drivers subsystem core. KMemleak detects this situation since loading/unloding some SCMI
 driver causes related devices to be created/destroyed without calling any device_release method.
