How to fix?

There is no fixed version for RHEL:7 qemu-kvm-common-rhev.

NVD Description

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

hw/ide/pci.c in QEMU before 5.1.1 can trigger a NULL pointer dereference because it lacks a pointer check before an ide_cancel_dma_sync call.
