Description
In the Linux kernel, the following vulnerability has been resolved: scsi: qedi: Fix use after free bug in qedi_remove() In qedi_probe() we call __qedi_probe() which initializes &qedi->recovery_work with qedi_recovery_handler() and &qedi->board_disable_work with qedi_board_disable_work(). When qedi_schedule_recovery_handler() is called, schedule_delayed_work() will finally start the work. In qedi_remove(), which is called to remove the driver, the following sequence may be observed: Fix this by finishing the work before cleanup in qedi_remove().
