How to fix?

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

NVD Description

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

Integer overflow in the net_tx_pkt_init function in hw/net/net_tx_pkt.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (QEMU process crash) via the maximum fragmentation count, which triggers an unchecked multiplication and NULL pointer dereference.
