    Subject[PATCH 5.2 113/135] sctp: fix memleak in sctp_send_reset_streams
    Date
    From: zhengbin <zhengbin13@huawei.com>

    [ Upstream commit 6d5afe20397b478192ed8c38ec0ee10fa3aec649 ]

    If the stream outq is not empty, need to kfree nstr_list.

    Fixes: d570a59c5b5f ("sctp: only allow the out stream reset when the stream outq is empty")
