Doc Text:
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.

Description OSIDB Bzimport 2026-09-17 18:56:49 UTC
In the Linux kernel, the following vulnerability has been resolved:

leds: lp5860: Fix a potential double-unlock

In lp5860_device_init(), if lp5860_init_dt() fails, an already unlocked
mutex is unlocked another time.

Slightly rework how the lock is taken/released to avoid this potential
double unlock.
