This issue was patched in RHSA-2024:2135.

NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-kvm-block-rbd package and not the qemu-kvm-block-rbd package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

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.
