Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: Fix not cleanup led when bt_init fails bt_init() calls bt_leds_init() to register led, but if it fails later, bt_leds_cleanup() is not called to unregister it. This can cause panic if the argument "bluetooth-power" in text is freed and then another led_trigger_register() tries to access it: BUG: unable to handle page fault for address: ffffffffc06d3bc0 RIP: 0010:strcmp+0xc/0x30 Call Trace: <TASK> led_trigger_register+0x10d/0x4f0 led_trigger_register_simple+0x7d/0x100 bt_init+0x39/0xf7 [bluetooth] do_one_initcall+0xd0/0x4e0
