Descripción

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> dpll: zl3073x: use __dpll_device_change_ntf() and remove change_work<br /> <br /> The change_work was introduced to send device change notifications<br /> from DPLL device callbacks without deadlocking on dpll_lock, since<br /> the callbacks are already invoked under that lock. Now that<br /> __dpll_device_change_ntf() is exported for callers that already<br /> hold dpll_lock, use it directly and remove the change_work<br /> infrastructure entirely.<br /> <br /> This eliminates a race condition where change_work could be<br /> re-scheduled after cancel_work_sync() during device teardown,<br /> potentially causing the handler to dereference a freed or NULL<br /> dpll_dev pointer.
