| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: ISO: Fix multiple init when debugfs is disabled\n\nIf bt_debugfs is not created successfully, which happens if either\nCONFIG_DEBUG_FS or CONFIG_DEBUG_FS_ALLOW_ALL is unset, then iso_init()\nreturns early and does not set iso_inited to true. 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.
