## Description

In the Linux kernel, the following vulnerability has been resolved:  RDMA/rxe: Fix "kernel NULL pointer dereference" error  When rxe_queue_init in the function rxe_qp_init_req fails, both qp->req.task.func and qp->req.task.arg are not initialized.  Because of creation of qp fails, the function rxe_create_qp will call rxe_qp_do_cleanup to handle allocated resource.  Before calling __rxe_do_task, both qp->req.task.func and qp->req.task.arg should be checked.
