Here are some example code snippets. Analyze the following code and CWE ID and the target value where 1 indicates the code has vulnerability and 0 indicates non-vulnerable code.
Example 1:
Code: static int aac_compat_ioctl(struct scsi_device *sdev, int cmd, void __user *arg)
{
struct aac_dev *dev = (struct aac_dev *)sdev->host->hostdata;
return aac_compat_do_ioctl(dev, cmd, (unsigned long)arg);
}
CWE ID: CWE-264
Target: 1
Example 2:
Code: void OnShowWidget(int routing_id, const gfx::Rect& initial_rect) {
content::BrowserThread::PostTask(
content::BrowserThread::UI, FROM_HERE,
base::BindOnce(&PendingWidgetMessageFilter::OnReceivedRoutingIDOnUI,
this, routing_id));
}
CWE ID: CWE-285
