Assigner: GitHub, Inc.

Description
KubeVirt is a virtual machine management add-on for Kubernetes. Prior to 1.7.0-beta.0, a logic flaw in the virt-controller allows an attacker to disrupt the control over a running VMI by creating a pod with the same labels as the legitimate virt-launcher pod associated with the VMI. This can mislead the virt-controller into associating the fake pod with the VMI, resulting in incorrect status updates and potentially causing a DoS (Denial-of-Service). This vulnerability is fixed in 1.7.0-beta.0.

Executive Summary

This vulnerability in KubeVirt's virt-controller is a logic flaw that allows an attacker to disrupt control over a running Virtual Machine Instance (VMI). The attacker can create a pod with the same labels as the legitimate virt-launcher pod associated with the VMI. This causes the virt-controller to mistakenly associate the fake pod with the VMI, leading to incorrect status updates and potentially causing a Denial-of-Service (DoS) condition.

Impact Analysis

The vulnerability can impact you by causing a Denial-of-Service (DoS) on your virtual machine instances managed by KubeVirt. This means that the control over running VMIs can be disrupted, potentially leading to downtime or unavailability of critical virtual machines.

Mitigation Strategies

Upgrade KubeVirt to version 1.7.0-beta.0 or later, as this version contains the fix for the vulnerability.
