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.
Security Fix(es):
* QEMU: msix: OOB access during mmio operations may lead to DoS (CVE-2020-13754)
* hivex: Buffer overflow when provided invalid node key length (CVE-2021-3504)
* QEMU: net: an assert failure via eth_get_gso_type (CVE-2020-27617)
* QEMU: net: infinite loop in loopback mode may lead to stack overflow (CVE-2021-3416)
* qemu: out-of-bound heap buffer access via an interrupt ID field (CVE-2021-20221)
