How to fix?

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 reachable assertion issue was found in the USB EHCI emulation code of QEMU. It could occur while processing USB requests due to missing handling of DMA memory map failure. A malicious privileged user within the guest may abuse this flaw to send bogus USB requests and crash the QEMU process on the host, resulting in a denial of service.
