In the Linux kernel, the following vulnerability has been resolved:
tls: Use __sk_dst_get() and dst_dev_rcu() in get_netdev_for_sock().
get_netdev_for_sock() is called during setsockopt(), so not under RCU.
Using sk_dst_get(sk)->dev could trigger UAF.
Let's use __sk_dst_get() and dst_dev_rcu().
Note that the only ->ndo_sk_get_lower_dev() user is bond_sk_get_lower_dev(), which uses RCU.
