CVE-2021-47547

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

net: tulip: de4x5: fix the problem that the array 'lp->phy[8]' may be out of bound

In line 5001, if all id in the array 'lp->phy[8]' is not 0, when the
'for' end, the 'k' is 8.

At this time, the array 'lp->phy[8]' may be out of bound.
