Summary
Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm packages provide the user-space component for running virtual machines that use KVM.
The following packages have been upgraded to a later upstream version: 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)
