  "details": "In the Linux kernel, the following vulnerability has been resolved:  Bluetooth: MGMT: free the mesh send cancel command when it is cancelled  mesh_send_cancel() queues the pending command with a NULL destroy callback, so it is only freed if send_cancel() runs. A cancelled entry is leaked, as _hci_cmd_sync_cancel_entry() does not release entry-\u003edata when there is no destroy callback, and hci_cmd_sync_clear() cancels every pending entry when the controller is unregistered. Nothing else reclaims it either: mgmt_pending_new() does not put the command on hdev-\u003emgmt_pending.  The leak also pins the socket reference taken by mgmt_pending_new(), so the mgmt socket is never released.  Free the command from a destroy callback.",
