In the Linux kernel, the following vulnerability has been resolved:
net/sched: netem: fix queue limit check to include reordered packets
The queue limit check in netemenqueue() uses q->tlen which only counts packets in the internal tfifo. Packets placed in sch->q by the reorder path (__qdiscenqueuehead) are not counted, allowing the total queue occupancy to exceed sch->limit under reordering.
Include sch->q.qlen in the limit check.
