Description

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