In the Linux kernel, the following vulnerability has been resolved: Bluetooth: MGMT: Fix adv monitor add failure cleanup hci_add_adv_monitor() publishes a new adv_monitor in hdev->adv_monitors_idr before the powered MSFT setup step. The MSFT offload add path can then fail either locally before the controller add command completes, or in the MSFT add callback. In the current queued management add flow, hci_cmd_sync_work() still invokes mgmt_add_adv_patterns_monitor_complete() with the original pending command after msft_add_monitor_pattern() returns. The buggy scenario involves two paths, with each column showing the order within that path: MSFT add handling MGMT completion 1. insert monitor and handle 1. receive sync error 2. send MSFT add command 2. call add-monitor completion 3. callback sees bad response 3. load cmd->user_data 4. callback frees monitor 4. read monitor->handle Local MSFT setup failures have the other half of the same ...
