[Impact]
It is found that it is possible to bypass rndis_wlan's security checks through
a vulnerability when given a large enough integer due to integer overflow,
possessing a threat to rndis_wlan driver users devices' memory.

[Backport]
It is a clean cherry-pick.

[Test]
Compile and smoke tested by loading the module and checking the dmesg.

[Potential Regression]
This patch is local to rndis_wlan driver.
