An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP,
WPA, WPA2, and WPA3 implementations accept plaintext A-MSDU frames as long
as the first 8 bytes correspond to a valid RFC1042 (i.e., LLC/SNAP) header
for EAPOL. An adversary can abuse this to inject arbitrary network packets
independent of the network configuration.
