CVE-2024-42128
Full vulnerability record from the local CVENow database.
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.

En este controlador, los LED se registran usando devm_led_classdev_register(), por lo que se cancelan automáticamente el registro después de que se realiza la eliminación() del módulo. led_classdev_unregister() llama a led_set_brightness() del módulo para apagar los LED y esa devolución de llamada usa mutex que ya fue destruido en remove() del módulo, así que use la API devm en su lugar."
