Echo: linux: security update to 6.1.137-1

medium Tenable Cloud Security Plugin ID 465170

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: phy: leds: fix memory leak A
 network restart test on a router led to an out-of-memory condition, which was traced to a memory leak in
 the PHY LED trigger code. The root cause is misuse of the devm API. The registration function
 (phy_led_triggers_register) is called from phy_attach_direct, not phy_probe, and the unregister function
 (phy_led_triggers_unregister) is called from phy_detach, not phy_remove. This means the register and
 unregister functions can be called multiple times for the same PHY device, but devm-allocated memory is
 not freed until the driver is unbound. This also prevents kmemleak from detecting the leak, as the devm
 API internally stores the allocated pointer. Fix this by replacing devm_kzalloc/devm_kcalloc with standard
 kzalloc/kcalloc, and add the corresponding kfree calls in the unregister path. (CVE-2025-37989)

Solution

Update the linux library and its related packages to version 6.1.137-1 or later.
