  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ntls: Use __sk_dst_get() and dst_dev_rcu() in get_netdev_for_sock().\n\nget_netdev_for_sock() is called during setsockopt(),\nso not under RCU.\n\nUsing sk_dst_get(sk)->dev could trigger UAF.\n\nLet's use __sk_dst_get() and dst_dev_rcu().\n\nNote that the only ->ndo_sk_get_lower_dev() user is\nbond_sk_get_lower_dev(), which uses RCU.",
