Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to errors in resource management within the Linux kernel's Bluetooth component, specifically in the bt init() and sock unregister() functions. This can lead to a panic if the "bluetooth-power" argument is freed and then accessed by another led trigger register() call. The problem arises because bt leds cleanup() is not called to unregister the led when bt init() fails.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
