In the Linux kernel, the following vulnerability has been resolved:scsi: ufs: core: Remove SCSI host only if addedIf host tries to remove ufshcd driver from a UFS device it would cause akernel panic if ufshcd_async_scan fails during ufshcd_probe_hba beforeadding a SCSI host with scsi_add_host and MCQ is enabled since SCSI hosthas been defered after MCQ configuration introduced by commit 0cab4023ec7b( scsi: ufs: core: Defer adding host to SCSI if MCQ is supported ).To guarantee that SCSI host is removed only if it has been added, set thescsi_host_added flag to true after adding a SCSI host and check whether itis set or not before removing it.
