Title
scsi: ufs: Avoid NULL CQE dereference when reporting invalid tags
Summary
In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: Avoid NULL CQE dereference when reporting invalid tags The single-doorbell completion path can call ufshcd_compl_one_cqe() with a NULL CQE. If no command is associated with the completion tag, the warning message dereferences the CQE while reporting the error. Avoid that dereference and include the invalid tag in the warning.
