Descriptions

In the Linux kernel, the following vulnerability has been resolved:

scsi: lpfc: Release hbalock before calling lpfc_worker_wake_up()

lpfc_worker_wake_up() calls the lpfc_work_done() routine, which takes the
hbalock. Thus, lpfc_worker_wake_up() should not be called while holding the
hbalock to avoid potential deadlock.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: lpfc: Libere hbalock antes de llamar a lpfc_worker_wake_up() lpfc_worker_wake_up() llama a la rutina lpfc_work_done(), que toma el hbalock. Por lo tanto, no se debe llamar a lpfc_worker_wake_up() mientras se mantiene presionado el hbalock para evitar un posible punto muerto.
