  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nbnxt_en: Propagate TPA buffer allocation failures in bnxt_queue_mem_alloc()\n\nbnxt_alloc_one_tpa_info_data() returns -ENOMEM as soon as one allocation\nfails. This leaves the remaining rxr-\u003erx_tpa[] entries zeroed.\n\nbnxt_queue_mem_alloc() discards that return value, so the partially\ninitialized ring is installed by bnxt_queue_start().\n\nSince the agg_id is picked by the hardware and bnxt_alloc_agg_idx maps\nit to a SW index in rxr-\u003erx_tpa[], it is possible that an uninitialized\nslot can be chosen which would hand a zero DMA address to the device.\n\nFix this by checking the return value of bnxt_alloc_one_tpa_info_data\nand unwinding, freeing the ring buffers.",
