KubeVirt Guest Agent DoS via Excessive Network Interface Reports

Published: 1/26/2026Modified: 2/3/2026

Also known as:GHSA-25mh-hp8x-cgrvGO-2026-4384

Description

A flaw was found in KubeVirt. A user within a virtual machine (VM), if the guest agent is active, can exploit this by causing the agent to report an excessive number of network interfaces. This action can overwhelm the system's ability to store VM configuration updates, effectively blocking changes to the Virtual Machine Instance (VMI). This allows the VM user to restrict the VM administrator's ability to manage the VM, leading to a Denial of Dervice for administrative operations.
