In the Linux kernel, the following vulnerability has been resolved:
ovpn: ensure socket is owned by ovpn before deref sk_user_data
Some subsystems, like BPF SOCKMAP, set sk_user_data without
actually setting the encap_type.
For this reason, we must make sure that the type is the
one ovpn expects before dereferencing sk_user_data.
Failing to do so may lead to out-of-bounds reads.
