CVE-2025-64324Public exploit

Host file read and write via incorrect chown

Published Nov 18, 2025 · Updated Feb 26, 2026

Permission handling in KubeVirt before 1.6.1 allows local users to read and write privileged host files through hostDisk DiskOrCreate. DiskImgCreator.mountHostDiskAndSetOwnership changes the ownership of an existing attacker-selected path instead of limiting that operation to a disk it creates. Exploitation requires the HostDisk feature gate and permission to create a VM using DiskOrCreate; affected 1.7 prereleases begin at 1.7.0-alpha.0.
