On May 11, 2021, the research paper Fragment and Forge: Breaking Wi-Fi Through Frame Aggregation and Fragmentation was made public. This paper discusses 12 vulnerabilities in the 802.11 standard. One vulnerability is in the frame aggregation functionality, two vulnerabilities are in the frame fragmentation functionality, and the other nine are implementation vulnerabilities. These vulnerabilities could allow an attacker to forge encrypted frames, which could in turn enable the exfiltration of sensitive data from a targeted device.
