SCSI Command Handling Flaw in Linux Kernel by Vendor

CVE-2023-53510

What is CVE-2023-53510?

A vulnerability exists in the Linux kernel's SCSI subsystem pertaining to the improper handling of SCSI commands by the ufshcd_queuecommand function. This situation can lead to redundant command submissions before a command is completed, potentially causing system instability and errors. Recent modifications have addressed this issue by altering how SCSI commands are processed, specifically during error handling, ensuring that the command pointer is not erroneously reset. Improvements in the ufshcd_release_scsi_cmd function prevent the clearing of important command data, thereby reducing the risk of timeout warnings during command execution.
