*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
mptcp: Use __sk_dst_get() and dst_dev_rcu() in mptcp_active_enable().<br />
<br />
mptcp_active_enable() is called from subflow_finish_connect(),<br />
which is icsk->icsk_af_ops->sk_rx_dst_set() and it&#39;s not always<br />
under RCU.<br />
