  "description": "In the Linux kernel, the following vulnerability has been resolved:  idpf: fix aux device unplugging when rdma is not supported by vport  If vport flags do not contain VIRTCHNL2_VPORT_ENABLE_RDMA, driver does not allocate vdev_info for this vport. This leads to kernel NULL pointer dereference in idpf_idc_vport_dev_down(), which references vdev_info for every vport regardless.  Check, if vdev_info was ever allocated before unplugging aux device.",
