In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Handle buffer allocation failure in bnxt_rx_ring_reset() bnxt_rx_ring_reset() frees the ring buffers and then reallocates them, ignoring the result. bnxt_alloc_one_rx_ring() can fail in bnxt_alloc_one_tpa_info_data(), which returns -ENOMEM on the first failed allocation and leaves the remaining rxr->rx_tpa[] entries zeroed. The error isn't propagated up, so the loop in bnxt_rx_ring_reset continues and at the end th…
