CVE-2023-42467

MEDIUM

QEMU < 8.0.0 - Denial of Service via Division by Zero in SCSI Disk Reset

Title source: llm
STIX 2.1

Description

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.
