Echo: linux: security update to 6.1.162-1

medium Tenable Self-Hosted Container Security Plugin ID 458860

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: leds: led-class: Only Add LED to
leds_list when it is fully ready Before this change the LED was added to leds_list before led_init_core()
gets called adding it the list before led_classdev.set_brightness_work gets initialized. This leaves a
window where led_trigger_register() of a LED's default trigger will call led_trigger_set() which calls
led_set_brightness() which in turn will end up queueing the *uninitialized*
led_classdev.set_brightness_work. This race gets hit by the lenovo-thinkpad-t14s EC driver which registers
2 LEDs with a default trigger provided by snd_ctl_led.ko in quick succession. The first
led_classdev_register() causes an async modprobe of snd_ctl_led to run and that async modprobe manages to
exactly hit the window where the second LED is on the leds_list without led_init_core() being called for
it, resulting in: ------------[ cut here ]------------ WARNING: CPU: 11 PID: 5608 at
