Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm-ma packages provide the user-space component for running virtual machines that use KVM on the IBM z Systems, IBM Power, and 64-bit ARM architectures.
Security Fix(es):
- QEMU: device_tree: heap buffer overflow while loading device tree blob (CVE-2018-20815)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
