      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/ionic: avoid OOB TX partner lookup for hwstamp RXQ\n\nThe dedicated hardware timestamp RX queue is allocated with q->index\nequal to lif->ionic->nrxqs_per_lif. The normal txqcqs array only\ncontains the regular queue pairs, so using that index to set rxq->partner\ncan read one entry past txqcqs[] and then write through the derived\npointer.\nOnly link RX/TX partners for normal queue-pair indexes. Leave the hwstamp\nRX queue unpaired, and make the XDP_TX path abort cleanly if an RX queue\nhas no TX partner.",
