Description

In the Linux kernel, the following vulnerability has been resolved: leds: an30259a: Use devm_mutex_init() for mutex initialization In this driver LEDs are registered using devm_led_classdev_register() so they are automatically unregistered after module's remove() is done. led_classdev_unregister() calls module's led_set_brightness() to turn off the LEDs and that callback uses mutex which was destroyed already in module's remove() so use devm API instead.

Affected products

• Linux kernel: from 4.20 before 6.6.39; from 6.7 before 6.9.9 — fixed in 6.6.39, 6.9.9
• Linux: 4.20 — fixed in 6.10

How to fix

Upgrade to a fixed version: Linux kernel 6.6.39, 6.9.9; Linux 6.10. Check the vendor advisory for mitigations.
