NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-source package and not the kernel-source package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

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().

Cancel recovery_work and board_disable_work in __qedi_remove().
