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