Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel’s SCSI subsystem, specifically within the UFS (Universal Storage Flash) core. The
ufshcd queuecommand() function may be invoked multiple times for a single SCSI command before its completion. This occurs because the code incorrectly handles the lrbp->cmd variable, potentially leading to a warning and unexpected behavior, particularly when a command times out. The issue is related to how SCSI error handling is managed, as seen in the scsi send eh cmnd() function. The fix involves modifying the command submission process and the ufshcd release scsi cmd() function to prevent incorrect handling of the lrbp->cmd variable in both successful and error scenarios.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
