Vulnerability from gsd
Modified

Details
In the Linux kernel, the following vulnerability has been resolved:
RDMA/core: Set send and receive CQ before forwarding to the driver
Preset both receive and send CQ pointers prior to call to the drivers and
overwrite it later again till the mlx4 is going to be changed do not
overwrite ibqp properties.
This change is needed for mlx5, because in case of QP creation failure, it
will go to the path of QP destroy which relies on proper CQ pointers.
