Description
A flaw was found in the Linux kernel's SCSI (Small Computer System Interface) core. During a SCSI host recovery, the scsi_run_host_queues() function may incorrectly ignore devices that are in a partially removed state. This oversight can cause pending requests for these devices to become stuck, leading to a hang in the device removal process. The primary consequence is a Denial of Service (DoS), as affected devices cannot be properly removed from the system.
