Overview\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nbnxt_en: Handle buffer allocation failure in bnxt_rx_ring_reset()\n\nbnxt_rx_ring_reset() frees the ring buffers and then reallocates them,\nignoring the result.\n\nbnxt_alloc_one_rx_ring() can fail in bnxt_alloc_one_tpa_info_data(), which\nreturns -ENOMEM on the first failed allocation and leaves the remaining\nrxr->rx_tpa[] entries zeroed.\n\nThe error isn't propagated up, so the loop in bnxt_rx_ring_reset\ncontinues and at the end the code re-enables TPA with partially\nunallocated rx_tpa array.\n\nThis means that when the agg_id from hardware is mapped to a SW index in\nrxr->rx_tpa[], an uninitialized slot can be chosen which would hand a\nzero DMA address to the device.\n\nFix this by falling back to a global reset, which is what the existing\ncode already does when other functions fail, but unlike the other\nfailure cases this particular failure has to return because TPA can't\nbe re-enabled since the allocation failed.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat
