Synopsis
The remote Azure Linux host is missing one or more security updates.Description
The version of qemu installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-4693 advisory.- A flaw was found in the QEMU Virtio PCI Bindings (hw/virtio/virtio-pci.c). An improper release and use of the irqfd for vector 0 during the boot process leads to a guest triggerable crash via vhost_net_stop().
This flaw allows a malicious guest to crash the QEMU process on the host. (CVE-2024-4693)
