Only link RX/TX partners for normal queue-pair indexes. Leave the hwstamp RX queue unpaired, and make the XDP_TX path abort cleanly if an RX queue has no TX partner.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>net/ionic: avoid OOB TX partner lookup for hwstamp RXQ</p> <p>The dedicated hardware timestamp RX queue is allocated with q-&gt;index equal to lif-&gt;ionic-&gt;nrxqs_per_lif.
