How to fix?

Upgrade RHEL:8 virt:rhel/libvirt-daemon-driver-nodedev to version 0:4.5.0-23.1.module+el8.0.0+3151+3ba813f9 or higher.
This issue was patched in RHSA-2019:1175.

NVD Description

Note: Versions mentioned in the description apply only to the upstream virt:rhel/libvirt-daemon-driver-nodedev package and not the virt:rhel/libvirt-daemon-driver-nodedev package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

In QEMU 3.1.0, load_device_tree in device_tree.c calls the deprecated load_image function, which has a buffer overflow risk.
