  "title": "bnge: return after auxiliary_device_uninit() in error path",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  bnge: return after auxiliary_device_uninit() in error path  When auxiliary_device_add() fails, the error block calls auxiliary_device_uninit() but does not return.  The uninit drops the last reference and synchronously runs bnge_aux_dev_release(), which sets bd-\u003Eauxr_dev = NULL and frees the underlying object.  The subsequent bd-\u003Eauxr_dev-\u003Enet = bd-\u003Enetdev then dereferences NULL, which is not a good thing to have happen when trying to clean up from an error.  Add the missing return, as the auxiliary bus documentation states is a requirement (seems that LLM tools read documentation better than humans do...)",
