CVE-2026-41685
Incus: Unbounded binary import disk exhaustion
Description
Incus is a system container and virtual machine manager. Prior to version 7.0.0, uploads of large amount of data by authenticated users can run the Incus server out of disk space, potentially taking down the host system. The impact here is limited for anyone using storage.images_volume and storage.backups_volume as those users will have large uploads be stored on those volumes rather than directly on the host filesystem. This is the default behavior on IncusOS. This issue has been patched in version 7.0.0.
