A use-after-free vulnerability was found in the am53c974 SCSI host bus adapter emulation of QEMU. It could occur in the esp_do_dma() 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 or potential code execution with the privileges of the QEMU process.
