In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix refcnt handling in __inet_hash_connect().
syzbot reported a warning in sk_nulls_del_node_init_rcu().
The commit 66b60b0c8c4a ("dccp/tcp: Unhash sk from ehash for tb2 alloc
failure after check_estalblished().") tried to fix an issue that an
unconnected socket occupies an ehash entry when bhash2 allocation fails.
In such a case, we need to revert changes done by check_established(),
which does not hold refcnt when inserting socket into ehash.
So, to revert the change, we need to __sk_nulls_add_node_rcu() instead
of sk_nulls_add_node_rcu().
Otherwise, sock_put() will cause refcnt underflow and leak the socket.
