"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: hci_sync: free the advertising instance on the failure and cancel paths\n\nadv_timeout_expire() hands a kmalloc()ed instance byte to\nhci_cmd_sync_queue() with a NULL destroy callback, and only\nadv_timeout_expire_sync() frees it. That leaks on two paths:\n\n - the return value is not checked, and hci_cmd_sync_queue() does not\n take ownership when it fails (-ENETDOWN, -ENODEV, -ENOMEM);\n\n - a cancelled entry is not released, as _hci_cmd_sync_cancel_entry()\n does not free entry->data when there is no destroy callback.\n hci_cmd_sync_clear() cancels every pending entry when the controller\n is unregistered.\n\nFree the buffer from a destroy callback, and in the caller when the entry\ncould not be queued at all."
