Pending analysis

Description

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