      "title": "net: atlantic: free stranded TX buffers on ring deinit",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: atlantic: free stranded TX buffers on ring deinit\n\naq_vec_deinit() drains the TX rings with a single aq_ring_tx_clean()\ncall, which frees at most AQ_CFG_TX_CLEAN_BUDGET (256) descriptors and\nstops at hw_head, which no longer moves once aq_vec_stop() has stopped\nthe hardware and NAPI. Completed descriptors beyond the budget and\neverything still posted in [hw_head, sw_tail) keep their skb or\nxdp_frame when the interface goes down: aq_vec_ring_free() then frees\nthe buffer ring and the references are lost for good.\n\nToday this is a silent memory leak on every interface down under\nTX/XDP_TX load. With the conversion of the RX path to page_pool posted\nfor net-next it becomes much more visible: XDP_TX frames carry fragment\nreferences on the RX ring's page_pool, so a single stranded frame keeps\nthe pool's inflight count above zero forever. page_pool_destroy() then\nnever completes, the pool is leaked together with its pages, and\n\"page_pool_release_retry() stalled pool shutdown\" is warned every 60\nseconds from that point on, on every ifdown, XDP detach or ring resize\nunder XDP_TX load.\n\nBring back aq_ring_tx_deinit() as it was before the removal and use it\nfor teardown again, with one extension: TX rings can hold xdp_frames\nnowadays, so release those too. They are returned with\nxdp_return_frame() since this runs in process context.",
