CVE-2026-23101

The CVE-2026-23101 issue affects the Linux kernel LED subsystem. The root cause is a race where an LED was added to leds_list before led_init_core() and before led_classdev.set_brightness_work is initialized. This could allow a default-trigger LED to call led_trigger_set() and queue an uninitiali...
