LIN1021-6509 : Security Advisory - qemu - CVE-2023-42467

Created: Sep 12, 2023 Updated: Jan 30, 2024

Resolved Date: Jan 28, 2024

Found In Version: 10.21.20.1

Severity: Standard

Applicable for: Wind River Linux LTS 21

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.
