    CVE-2023-42467

    Published: 11 Sept 2023Last Modified: 12 Aug 2026

    Summary:

    Details: QEMU through 8.0.0 could trigger a division by zero in scsi_disk_reset in hw/scsi/scsi-disk.c because scsi_disk_emulate_mode_select does not prevent s->qdev.blocksize from being 256. This stops QEMU and the guest immediately.
