In the Linux kernel, the following vulnerability has been resolved:
bnxt_en: Propagate RX ring init failures in bnxt_init_nic()
bnxt_init_rx_rings() returns an error when bnxt_alloc_one_rx_ring() fails, but bnxt_init_nic() discards that return value and calls bnxt_init_chip(), which enables TPA.
If an allocation fails, this could leave rxr->rx_tpa[] partially zeroed and TPA would be enabled over an array with zeroed entries. This would lead to a zeroed DMA address being handed out if the agg_idx is translated to a SW index at a zeroed entry.
Fix this by propagating the error out of bnxt_init_nic(). Both callers already check its return value and unwind with bnxt_free_skbs() and bnxt_free_mem(), which tolerate a partially initialized RX ring.
