  "details": "In the Linux kernel, the following vulnerability has been resolved:  mac802154: hold an interface reference across the scan worker  mac802154_scan_worker() captures the scanning sub-interface under RCU and then keeps dereferencing sdata-\u003edev after rcu_read_unlock() and outside the rtnl -- in the failure traces, in mac802154_transmit_beacon_req() (skb-\u003edev = sdata-\u003edev), and in the end_scan cleanup. Nothing keeps that netdev alive across the worker iteration.  A concurrent DEL_INTERFACE or PHY removal can unregister the interface once the worker drops the rtnl between its two drv_set_channel() sections. unregister_netdevice() frees the netdev asynchronously from netdev_run_todo() with the rtnl already dropped, so neither holding the rtnl nor the per-PHY IEEE802154_IS_SCANNING flag prevents a stale worker iteration from dereferencing the freed netdev -- a KASAN slab-use-after-free, reachable by racing TRIGGER_SCAN against DEL_INTERFACE (both CAP_NET_ADMIN).  Pin the netdev with netdev_hold() while the RCU read lock is still held, and release it at every worker exit.",
