Description :In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
net\/sched: dualpi2: fix GSO backlog accounting<\/p>\n
When DualPI2 splits a GSO skb into N segments, it propagates N
\nadditional packets to its parent before returning NET_XMIT_SUCCESS.
\nThe parent then accounts for the original skb once more, leaving its
\nqlen one larger than the number of packets actually queued.<\/p>\n
With QFQ as the parent, after all real packets are dequeued, QFQ still
\nhas a non-zero qlen while its in-service aggregate has no active
\nclasses. qfq_choose_next_agg() returns NULL and qfq_dequeue() passes
\nthe result to qfq_peek_skb(), causing a NULL pointer dereference.<\/p>\n
Follow the same pattern used by tbf_segment() and taprio: count only
\nsuccessfully queued segments, propagate the difference between the
\noriginal skb and those segments, and return NET_XMIT_SUCCESS whenever
\nat least one segment was queued.<\/p>\n
Severity: 0.0 | NA<\/p>\n
