This update affects Rocky Linux 8.
A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE list
Kernel-based Virtual Machine (KVM) offers a full virtualization solution for Linux on numerous hardware platforms. The virt:Rocky Linux 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)
