The URB may complete on another CPU\nin softirq context before usb_submit_urb() returns in the submitter,\nso by the time the submitter reads skb->len the skb has already been\nqueued to the per-CPU completion_queue and freed by net_tx_action():\n\n  CPU A (xmit)                      CPU B (USB completion softirq)\n  ------------                      ------------------------------\n  dev->tx_skb = skb;\n  usb_submit_urb()      --+\n                          |-------> write_bulk_callback()\n                          |           dev_kfree_skb_irq(dev->tx_skb)\n                          |         net_tx_action()\n                          |           napi_skb_cache_put()   <-- free\n  netdev->stats.tx_bytes  |\n    += skb->len;          <-- UAF read\n\nFix it by caching skb->len before submitting the URB and using the\ncached value when updating the tx_bytes counter.\n\nThe pre-existing tx_bytes semantics are preserved: the counter tracks\nthe original frame length (skb->len), not the ETH_ZLEN/USB-alignment\npadded \"count\" value that is handed to the device.  Changing that\nwould be a user-visible accounting change and is out of scope for\nthis UAF fix.",
