NVD 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->auxr_dev = NULL and frees the underlying object. The subsequent bd->auxr_dev->net = bd->netdev 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...)
