{"schema":"threatline.record/2","record":{"id":"CVE-2026-97572","aliases":[],"summary":"bnxt_en: Propagate RX ring init failures in bnxt_init_nic()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbnxt_en: Propagate RX ring init failures in bnxt_init_nic()\n\nbnxt_init_rx_rings() returns an error when bnxt_alloc_one_rx_ring()\nfails, but bnxt_init_nic() discards that return value and calls\nbnxt_init_chip(), which enables TPA.\n\nIf an allocation fails, this could leave rxr->rx_tpa[] partially zeroed\nand TPA would be enabled over an array with zeroed entries. 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.","categories":["Operating
