{"id":"DEBIAN-CVE-2023-54100","details":"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-\u003erecovery_work with qedi_recovery_handler() and &qedi-\u003eboard_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().
