  "details": "In the Linux kernel, the following vulnerability has been resolved:  Bluetooth: hci_sync: Fix accept list UAF during suspend  hci_update_event_filter_sync() walks hdev-\u003eaccept_list while sending a synchronous HCI command for each remote-wakeup device.  The suspend path holds hdev-\u003ereq_lock, but accept-list updates are serialized by hdev-\u003elock. Consequently, remove_device() can free the current list entry during the controller wait.  The following interleaving causes the use-after-free:    hci_update_event_filter_sync()    remove_device()   fetch accept-list entry   hci_set_event_filter_sync()     wait for controller response    hci_dev_lock()                                     list_del()                                     kfree()                                     hci_dev_unlock()   read the freed list.next  KASAN reported:    BUG: KASAN: slab-use-after-free in hci_suspend_sync+0x835/0x910   Read of size 8 at addr ffff88810bec8440 by task kworker/0:1/10   Workqueue: events vhci_suspend_work   Call Trace:    hci_suspend_sync+0x835/0x910    hci_suspend_dev+0x182/0x450    process_one_work+0x661/0x1090    worker_thread+0x45b/0xd10    Allocated by task 86:    hci_bdaddr_list_add_with_flags+0x1a8/0x400    add_device+0x381/0x820    hci_sock_sendmsg+0x1033/0x1ea0    Freed by task 91:    kfree+0x131/0x3c0    remove_device+0x429/0xb70    hci_sock_sendmsg+0x1033/0x1ea0  Snapshot the remote-wakeup addresses under hdev-\u003elock.  Release the lock before sending HCI commands.  Clear the controller event filter before building the snapshot, and skip allocation and the second list traversal when there are no matching entries.  This preserves the original filter and scan-state updates without retaining an accept-list node across a controller wait.",
