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

  - Incus is a system container and virtual machine manager. Prior to version 6.23.0, a specially crafted
    storage bucket backup can be used by an user with access to Incus' storage bucket feature to crash the
    Incus daemon. Repeated use of this attack can be used to keep the server offline causing a denial of
    service of the control plane API. This does not impact any running workload, existing containers and
    virtual machines will keep operating. Version 6.23.0 fixes the issue. (CVE-2026-33743)

The remote Fedora 42 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-4481307278 advisory.
