Summary

Kernel-based Virtual Machine (KVM) offers a full virtualization solution for Linux on numerous hardware platforms. The virt:rhel module contains packages which provide user-space components used to run virtual machines using KVM. The packages also provide APIs for managing and interacting with the virtualized systems.
The following packages have been upgraded to a later upstream version: qemu-kvm (6.2.0). (BZ#2066828)
Security Fix(es):
* QEMU: fdc: heap buffer overflow in DMA read data transfers(CVE-2021-3507)
* libvirt: missing locking in nwfilterConnectNumOfNWFilters can lead to denial of service (CVE-2022-0897)
* libguestfs: Buffer overflow in get_keys leads to DoS (CVE-2022-2211)
* swtpm: Unchecked header size indicator against expected size (CVE-2022-23645)
