Title
RDMA/rxe: Fix "kernel NULL pointer dereference" error
Summary
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.
