The append then writes a struct nfc_target past the end of the\narray (a slab out-of-bounds write), and nfc_targets_found() goes on to\nwalk the array with the inflated count:\n\n BUG: KASAN: slab-out-of-bounds in nci_add_new_protocol+0x94/0x2ac [nci]\n Write of size 2 at addr ffff0000c7299a18 by task kworker/u8:0/12\n Workqueue: nfc0_nci_rx_wq nci_rx_work [nci]\n Call trace:\n nci_add_new_protocol+0x94/0x2ac [nci]\n nci_ntf_packet+0xddc/0x11a0 [nci]\n nci_rx_work+0x15c/0x1e0 [nci]\n process_one_work+0x2dc/0x500\n worker_thread+0x240/0x460\n kthread+0x1c0/0x1d0\n ret_from_fork+0x10/0x20\n\n The buggy address belongs to the cache kmalloc-2k of size 2048\n The buggy address is located 1024 bytes to the right of\n allocated 1560-byte region [ffff0000c7299000, ffff0000c7299618)\n\nGuard nci_target_auto_activated() with the same check used by\nnci_add_new_target()."
