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