Updated

In the Linux kernel, the following vulnerability has been resolved:

wifi: ipw2200: fix memory leak in ipwwdevinit()

In the error path of ipwwdevinit(), exception value is returned, and the memory applied for in the function is not released. Also the memory is not released in ipwpciprobe(). As a result, memory leakage occurs. So memory release needs to be added to the error path of ipwwdevinit().
