Published Nov 18, 2025CWE-200EPSS 0.22%

Overview

CVE-2025-64324 is a high-severity vulnerability. It was published on November 18, 2025 and has a CVSS 3.1 base score of 7.7 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.7, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

KubeVirt is a virtual machine management add-on for Kubernetes. The `hostDisk` feature in KubeVirt allows mounting a host file or directory owned by the user with UID 107 into a VM. However, prior to version 1.6.1 and 1.7.0, the implementation of this feature and more specifically the `DiskOrCreate` option (which creates a file if it doesn't exist) has a logic bug that allows an attacker to read and write arbitrary files owned by more privileged users on the host system. Versions 1.6.1 and 1.7.0 fix the issue.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
