Description
In the Linux kernel, the following vulnerability has been resolved:
net: sched: fix ordering of qlen adjustment
Changes to sch->q.qlen around qdisc_tree_reduce_backlog() need to happen _before_ a call to said function because otherwise it may fail to notify parent qdiscs when the child is about to become empty.
