RLSA-2026:18748

Synopsis

Moderate: libvirt security update

Description

Kernel-based Virtual Machine (KVM) offers a full virtualization solution forLinux on numerous hardware platforms. The virt:rhel module contains packageswhich 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):

* libvirt: Denial of service in XML parsing (CVE-2025-12748)
