Descriptions

In the Linux kernel, the following vulnerability has been resolved: net: sched: fix possible refcount leak in tc_new_tfilter() tfilter_put need to be called to put the refount got by tp->ops->get to
avoid possible refcount leak when chain->tmplt_ops != NULL and
chain->tmplt_ops != tp->ops.
