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.
