REDHAT-BUG-2238291
First published: Mon Sep 11 2023(Updated: )
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. <a href="https://gitlab.com/thuth/qemu/-/commit/3f91104484e5bf55b56d7e1b039a4a5a17d0c1a7">https://gitlab.com/thuth/qemu/-/commit/3f91104484e5bf55b56d7e1b039a4a5a17d0c1a7</a> <a href="https://gitlab.com/qemu-project/qemu/-/issues/1813">https://gitlab.com/qemu-project/qemu/-/issues/1813</a>
