The (1) BMDMA and (2) AHCI HBA interfaces in the IDE functionality in QEMU
1.0 through 2.1.3 have multiple interpretations of a function’s return
value, which allows guest OS users to cause a host OS denial of service
(memory consumption or infinite loop, and system crash) via a PRDT with
zero complete sectors, related to the bmdma_prepare_buf and
ahci_dma_prepare_buf functions.
