bnxt_queue_mem_alloc() shallow copies the live RX ring into the clone:<\/p>\n
memcpy(clone, rxr, sizeof(*rxr));<\/p>\n
the code currently clears pointers that the clone owns (such as
\nrx_agg_bmap), but rx_tpa and rx_tpa_idx_map are left pointing at memory
\nof the live ring that was cloned.<\/p>\n
If an allocation failure happens later and the err_free_tpa_info label
\nis taken, the live ring’s memory can be freed while still in use.<\/p>\n
Fix this by initializing the clone’s pointers to NULL to prevent live
\nring state from being freed inadvertently.<\/p>\n","protected":false},"excerpt":{"rendered":"
