Vulnerability from fkie_nvd - Published: 2024-10-21 20:15 - Updated: 2026-06-17 05:16
Severity
Summary
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]
