UBUNTU-CVE-2024-4693

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 vhostnetstop(). This flaw allows a malicious guest to crash the QEMU process on the host.
