Description
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.
A flaw was found in the Linux kernel, where the WiFi implementations accept plaintext A-MSDU frames as long as the first 8 bytes correspond to a valid RFC1042 (ex., LLC/SNAP) header for EAPOL. The highest threat from this vulnerability is to integrity.
