"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nleds: led-class: Only Add LED to leds_list when it is fully ready\n\nBefore this change the LED was added to leds_list before led_init_core()\ngets called adding it the list before led_classdev.set_brightness_work gets\ninitialized.\n\nThis leaves a window where led_trigger_register() of a LED's default\ntrigger will call led_trigger_set() which calls led_set_brightness()\nwhich in turn will end up queueing the *uninitialized*\nled_classdev.set_brightness_work.\n\nThis race gets hit by the lenovo-thinkpad-t14s EC driver which registers\n2 LEDs with a default trigger provided by snd_ctl_led.ko in quick\nsuccession. The first led_classdev_register() causes an async modprobe of\nsnd_ctl_led to run and that async modprobe manages to exactly hit\nthe window where the second LED is on the leds_list without led_init_core()\nbeing called for it, resulting in:\n\n ------------[ cut here ]------------\n WARNING: CPU: 11 PID: 5608 at kernel/workqueue.c:4234 __flush_work+0x344/0x390\n Hardware name: LENOVO 21N2S01F0B/21N2S01F0B, BIOS N42ET93W (2.23 ) 09/01/2025\n ...\n Call trace:\n __flush_work+0x344/0x390 (P)\n flush_work+0x2c/0x50\n led_trigger_set+0x1c8/0x340\n led_trigger_register+0x17c/0x1c0\n led_trigger_register_simple+0x84/0xe8\n snd_ctl_led_init+0x40/0xf88 [snd_ctl_led]\n do_one_initcall+0x5c/0x318\n do_init_module+0x9c/0x2b8\n load_module+0x7e0/0x998\n\nClose the race window by moving the adding of the LED to leds_list to\nafter the led_init_core() call."
