NVD Description
Note: Versions mentioned in the description apply only to the upstream qemu-img package and not the qemu-img package as distributed by Centos.

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.
