Description

A flaw was found in the Linux kernel's leds: lp5860 component. This vulnerability occurs when the lp5860_device_init() function attempts to unlock a mutex that has already been released, specifically if the lp5860_init_dt() function fails. Such a double-unlock operation can lead to unexpected system behavior or instability, potentially resulting in a denial of service (DoS) condition.
