A cancelled entry is\nleaked, as _hci_cmd_sync_cancel_entry() does not release entry->data when\nthere is no destroy callback, and hci_cmd_sync_clear() cancels every\npending entry when the controller is unregistered. Nothing else reclaims\nit either: mgmt_pending_new() does not put the command on\nhdev->mgmt_pending.\n\nThe leak also pins the socket reference taken by mgmt_pending_new(), so\nthe mgmt socket is never released.\n\nFree the command from a destroy callback.","state":0,"publishedAt":"2026-09-17T16:07:53.435+00:00","modifiedAt":"2026-10-19T09:00:30.044+00:00","affected":[{"ecosystem":"Vendor
