remote 802.15.4 frames do not reach ieee802154_remove_interfaces().\nAC:L - The attacker controls both sides of the race by concurrently sending traffic (sendmmsg on AF_IEEE802154) while deleting the radio/hardware; syzbot reliably reproduced the crash without external timing dependencies.\nPR:L - With mac802154_hwsim loaded, CAP_NET_ADMIN in a user namespace suffices to bring up wpan interfaces, transmit packets, and issue MAC802154_HWSIM_CMD_DEL_RADIO (GENL_UNS_ADMIN_PERM); AF_IEEE802154 sockets also require only namespace CAP_NET_ADMIN/CAP_NET_RAW.\nUI:N - No victim interaction is required; the attacker triggers the race entirely through their own netlink and socket operations without needing another user to perform any action.\nS:U - Impact is confined to kernel memory corruption and privilege boundaries within the same kernel; this is not a VM escape, IOMMU bypass, or cross-security-authority boundary violation.\nC:H - The RCU list walk in ieee802154_wake_queue() dereferences poisoned/freed list nodes (KASAN wild-memory-access at dead000000000218), constituting use-after-free class memory corruption that can expose adjacent kernel heap contents.\nI:H - Corrupted list traversal can pass attacker-influenced sdata/netdev pointers into netif_wake_queue(), enabling heap corruption primitives and potential control-flow hijacking beyond a simple crash.\nA:H - The syzbot reproducer causes a general protection fault kernel oops in ieee802154_release_queue();
