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

  - Incus is a system container and virtual machine manager. An issue in versions prior to 6.0.6 and 6.19.0
    affects any Incus user in an environment where an unprivileged user may have root access to a container
    with an attached custom storage volume that has the `security.shifted` property set to `true` as well as
    access to the host as an unprivileged user. The most common case for this would be systems using `incus-
    user` with the less privileged `incus` group to provide unprivileged users with an isolated restricted
    access to Incus. Such users may be able to create a custom storage volume with the necessary property
    (depending on kernel and filesystem support) and can then write a setuid binary from within the container
    which can be executed as an unprivileged user on the host to gain root privileges. A patch for this issue
    is expected in versions 6.0.6 and 6.19.0. As a workaround, permissions can be manually restricted until a
    patched version of Incus is deployed. (CVE-2025-64507)

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Cross-Site Request Forgery (CSRF) in LXD-UI in Canonical LXD versions >= 5.0 on Linux allows an attacker
    to create and start container instances without user consent via crafted HTML form submissions exploiting
    client certificate authentication. (CVE-2025-54286)

  - Template Injection in instance snapshot creation component in Canonical LXD (>= 4.0) allows an attacker
    with instance configuration permissions to read arbitrary files on the host system via specially crafted
    snapshot pattern templates using the Pongo2 template engine. (CVE-2025-54287)

  - Information Spoofing in devLXD Server in Canonical LXD versions 4.0 and above on Linux container platforms
    allows attackers with root privileges within any container to impersonate other containers and obtain
    their metadata, configuration, and device information via spoofed process names in the command line.
    (CVE-2025-54288)

  - Privilege Escalation in operations API in Canonical LXD <6.5 on multiple platforms allows attacker with
    read permissions to hijack terminal or console sessions and execute arbitrary commands via WebSocket
    connection hijacking format (CVE-2025-54289)

    Package        : incus     CVE ID         : CVE-2025-64507

    It was discovered that Incus, a system container and virtual machine     manager, is prone to a local privilege escalation vulnerability     unprivileged users are allowed access to Incus through incus-user.

    For the stable distribution (trixie), this problem has been fixed in     version 6.0.4-2+deb13u2.

    We recommend that you upgrade your incus packages.

    For the detailed security status of incus please refer to its security     tracker page at:

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Incus is a system container and virtual machine manager. An issue in versions prior to 6.0.6 and 6.19.0     affects any Incus user in an environment where an unprivileged user may have root access to a container     with an attached custom storage volume that has the `security.shifted` property set to `true` as well as     access to the host as an unprivileged user. The most common case for this would be systems using `incus-     user` with the less privileged `incus` group to provide unprivileged users with an isolated restricted     access to Incus.

Note that Nessus relies on the presence of the package as reported by the vendor.

    Package        : lxd     CVE ID         : CVE-2025-64507

    It was discovered that LXD, a system container and virtual machine     manager, is prone to a local privilege escalation vulnerability if     unprivileged users are allowed to access LXD through lxd-user.

    For the oldstable distribution (bookworm), this problem has been fixed     in version 5.0.2-5+deb12u2.

    We recommend that you upgrade your lxd packages.
