CVE-2023-53510

In the Linux kernel, the following vulnerability has been resolved:

scsi: ufs: core: Fix handling of lrbp->cmd

ufshcd_queuecommand() may be called two times in a row for a SCSI command
before it is completed. Hence make the following changes:

 - In the functions that submit a command, do not check the old value of
   lrbp->cmd nor clear lrbp->cmd in error paths.

 - In ufshcd_release_scsi_cmd(), do not clear lrbp->cmd.

See also scsi_send_eh_cmnd().

This commit prevents that the following appears if a command times out:
