softirq; on TSN/automotive/industrial gateways where taprio+qfq is already deployed, any remote peer can trigger it by sending traffic that causes egress through the gated queues.\nAC:L - Once taprio is configured with a non-work-conserving child such as qfq on the software path (no full offload, TXTIME_ASSIST disabled), peek followed by the incorrect direct `dequeue()` deterministically orphans the stashed skb, desyncs qlen/backlog, and re-enters qfq on an emptied list; the attacker fully controls triggering traffic with no uncontrollable races.\nPR:N - Installing taprio and grafting a qfq child requires CAP_NET_ADMIN via RTM_NEWQDISC, but on reasonably deployed TSN/industrial systems where operators have already configured this stack, triggering the bug requires only the ability to

entirely within the host kernel's security authority; this is not a VM escape, container breakout, or IOMMU/DMA boundary bypass.\nC:N - The published failure mode is a NULL pointer dereference in qfq after taprio mishandles the peek stash; although the peeked skb is orphaned and child counters desync, there is no use-after-free, out-of-bounds read, or demonstrated arbitrary kernel memory disclosure primitive.\nI:L - Calling `child->ops->dequeue()` instead of `qdisc_dequeue_peeked()` orphans the peek-stashed skb and corrupts the child qdisc's qlen/backlog accounting before the fatal qfq re-entry, enabling attacker-driven mis-accounting of queued traffic on the affected egress path prior to panic.\nA:H - With a qfq child the desynchronized dequeue path dereferences NULL from
