A NULL pointer dereference issue was found in the SCSI emulation support of QEMU. It could occur in the scsi_req_continue() function in hw/scsi/scsi-bus.c while handling the 'Information Transfer' command (CMD_TI) of the am53c974 SCSI host bus adapter. A privileged guest user may abuse this issue to crash the QEMU process on the host, resulting in a denial of service condition.
