      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nmac802154: hold an interface reference across the scan worker\n\nmac802154_scan_worker() captures the scanning sub-interface under RCU\nand then keeps dereferencing sdata->dev after rcu_read_unlock() and\noutside the rtnl -- in the failure traces, in\nmac802154_transmit_beacon_req() (skb->dev = sdata->dev), and in the\nend_scan cleanup. Nothing keeps that netdev alive across the worker\niteration.\n\nA concurrent DEL_INTERFACE or PHY removal can unregister the interface\nonce the worker drops the rtnl between its two drv_set_channel()\nsections. unregister_netdevice() frees the netdev asynchronously from\nnetdev_run_todo() with the rtnl already dropped, so neither holding the\nrtnl nor the per-PHY IEEE802154_IS_SCANNING flag prevents a stale worker\niteration from dereferencing the freed netdev -- a KASAN\nslab-use-after-free, reachable by racing TRIGGER_SCAN against\nDEL_INTERFACE (both CAP_NET_ADMIN).\n\nPin the netdev with netdev_hold() while the RCU read lock is still held,\nand release it at every worker exit.",
