LIN1023-2064 : Security Advisory - qemu - CVE-2023-42467

Created: Sep 11, 2023    Updated: Feb 6, 2026
Resolved Date: Nov 16, 2023
Found In Version: 10.23.30.1
Severity: Standard
Applicable for: Wind River Linux LTS 23
Component/s: Userspace

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.
