Upgrade AlmaLinux:9 qemu-kvm-block-rbd to version 17:8.2.0-11.el9_4 or higher.
This issue was patched in ALSA-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 AlmaLinux.
See How to fix? for AlmaLinux: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.
