There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Incus is a system container and virtual machine manager. In versions before 7.0.0, missing validation
    logic in the storage volume import logic allows an authenticated user with access to the storage volume
    feature to cause the Incus daemon to crash. The custom volume backup import subsystem contains a nil-
    pointer dereference vulnerability during import operations. In the snapshot import loop, the daemon
    iterates over entries from `srcBackup.Config.VolumeSnapshots` and assumes that each slice element is
    initialized, then dereferences fields such as `Name`, `Config`, `Description`, `CreatedAt`, and
    `ExpiresAt` without first validating the element itself. Because the yaml unmarshaler accepts explicit
    null array elements from an attacker-controlled index.yaml and converts them into nil pointers inside the
    slice, an attacker can supply a backup archive containing a null entry in the volume_snapshots array. This
    causes a nil-pointer dereference during custom volume import and terminates the daemon, resulting in
    denial of service on the affected node. Repeated use of this issue can be used to keep Incus offline,
    causing a denial of service. This issue is fixed in version 7.0.0. (CVE-2026-40197)

The remote Debian 12 / 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6247 advisory.

    Multiple security issues were discovered in LXD, a system container     and virtual machine manager, which could result in denial of service.

    For the oldstable distribution (bookworm), these problems have been fixed     in version 5.0.2-5+deb12u6.

    For the stable distribution (trixie), these problems have been fixed in     version 5.0.2+git20231211.1364ae4-9+deb13u6.

    We recommend that you upgrade your lxd packages.
