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

  - In the Linux kernel, the following vulnerability has been resolved: idpf: fix double free and use-after-
    free in aux device error paths When auxiliary_device_add() fails in idpf_plug_vport_aux_dev() or
    idpf_plug_core_aux_dev(), the err_aux_dev_add label calls auxiliary_device_uninit() and falls through to
    err_aux_dev_init. The uninit call will trigger put_device(), which invokes the release callback
    (idpf_vport_adev_release / idpf_core_adev_release) that frees iadev. The fall-through then reads adev->id
    from the freed iadev for ida_free() and double-frees iadev with kfree(). Free the IDA slot and clear the
    back-pointer before uninit, while adev is still valid, then return immediately. Commit 65637c3a1811
    ("idpf: fix UAF in RDMA core aux dev deinitialization") fixed the same use-after-free in the matching
    unplug path in this file but missed both probe error paths. (CVE-2026-53286)

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