net: sctp: possible dereference after freeing

[Geyslan GregÃrio Bem]

Hi maintainers,

I would like to know if these are catches:

/net/sctp/endpointola.c (281)
static void sctp_endpoint_destroy(struct sctp_endpoint *ep)
{
    struct sock *sk;
...
    kfree(ep);
    SCTP_DBG_OBJCNT_DEC(ep);
}

The 'ep' object counter is being decremented?! Is the kfree to be there indeed?
Let me know what was intended here.

Same here:
/net/sctp/endpointola.c (165)
static void sctp_transport_destroy_rcu(struct rcu_head *head)
{
    struct sctp_transport *transport;
...
    kfree(transport);
    SCTP_DBG_OBJCNT_DEC(transport);
}

Regards,
