In the Linux kernel, the following vulnerability has been resolved:

RDMA/siw: Fix duplicated reported IW_CM_EVENT_CONNECT_REPLY event

If siw_recv_mpa_rr returns -EAGAIN, it means that the MPA reply hasn't
been received completely, and should not report IW_CM_EVENT_CONNECT_REPLY
in this case. This may trigger a call trace in iw_cm. A simple way to
trigger this:
 server: ib_send_lat
 client: ib_send_lat -R <server_ip>

The call trace looks like this:
