There is no fixed version for Centos:7 qemu-guest-agent.

NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-guest-agent package and not the qemu-guest-agent package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

A double free vulnerability was found in QEMU virtio devices (virtio-gpu, virtio-serial-bus, virtio-crypto), where the mem_reentrancy_guard flag insufficiently protects against DMA reentrancy issues. This issue could allow a malicious privileged guest user to crash the QEMU process on the host, resulting in a denial of service or allow arbitrary code execution within the context of the QEMU process on the host.
