The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:1762 advisory.

    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.
