This means that a  \nsubsequent call to iso_init() will result in duplicate calls to  \nproto_register(), bt_sock_register(), etc.  \n  \nWith CONFIG_LIST_HARDENED and CONFIG_BUG_ON_DATA_CORRUPTION enabled, the  \nduplicate call to proto_register() triggers this BUG():  \n  \n  list_add double add: new=ffffffffc0b280d0, prev=ffffffffbab56250,  \n    next=ffffffffc0b280d0.  \n  ------------[ cut here ]------------  \n  kernel BUG at lib/list_debug.c:35!  \n  Oops: invalid opcode: 0000 [#1] PREEMPT SMP PTI  \n  CPU: 2 PID: 887 Comm: bluetoothd Not tainted 6.10.11-1-ao-desktop #1  \n  RIP: 0010:__list_add_valid_or_report+0x9a/0xa0  \n  ...  \n    __list_add_valid_or_report+0x9a/0xa0  \n    proto_register+0x2b5/0x340  \n    iso_init+0x23/0x150 [bluetooth]  \n    set_iso_socket_func+0x68/0x1b0 [bluetooth]  \n    kmem_cache_free+0x308/0x330  \n    hci_sock_sendmsg+0x990/0x9e0 [bluetooth]  \n    __sock_sendmsg+0x7b/0x80  \n    sock_write_iter+0x9a/0x110  \n    do_iter_readv_writev+0x11d/0x220  \n    vfs_writev+0x180/0x3e0  \n    do_writev+0xca/0x100  \n  ...  \n  \nThis change removes the early return. The check for iso_debugfs being  \nNULL was unnecessary, it is always NULL when iso_inited is false. \nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n  \"Detection Date\": \"29 Oct 2024\",\n  \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2024-10-29T03:03:12.000000Z"}]}
