{"schema":"threatline.record/2","record":{"id":"CVE-2026-97574","aliases":[],"summary":"bnxt_en: Don't free the live ring's TPA state on queue restart failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbnxt_en: Don't free the live ring's TPA state on queue restart failure\n\nbnxt_queue_mem_alloc() shallow copies the live RX ring into the clone:\n\n  memcpy(clone, rxr, sizeof(*rxr));\n\nthe 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.\n\nIf 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.\n\nFix this by initializing the clone's pointers to NULL to prevent live\nring state from being freed inadvertently.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
