This would\nlead to a zeroed DMA address being handed out if the agg_idx is\ntranslated to a SW index at a zeroed entry.\n\nFix this by propagating the error out of bnxt_init_nic(). Both callers\nalready check its return value and unwind with bnxt_free_skbs() and\nbnxt_free_mem(), which tolerate a partially initialized RX ring.","state":0,"publishedAt":"2026-09-25T10:21:56.826+00:00","modifiedAt":"2026-10-19T09:09:34.905+00:00","affected":[{"ecosystem":"Vendor
