qemu-kvm (7.0.0). (BZ#2064757)

Security Fix(es):

* QEMU: hcd-ehci: DMA reentrancy issue leads to use-after-free
(CVE-2021-3750)

* QEMU: fdc: heap buffer overflow in DMA read data transfers
(CVE-2021-3507)

* QEMU: intel-hda: segmentation fault due to stack overflow (CVE-2021-3611)

* QEMU: NULL pointer dereference in pci_write() in hw/acpi/pcihp.c
(CVE-2021-4158)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.
