The IEEE 802.11 standard sometimes enables an adversary to trick a victim into connecting to an unintended or untrusted network with Home WEP, Home WPA3 SAE-loop. Enterprise 802.1X/EAP, Mesh AMPE, or FILS, aka an "SSID Confusion" issue. This occurs because the SSID is not always used to derive the pairwise master key or session keys, and because there is not a protected exchange of an SSID during a 4-way handshake.

A flaw was found in the Linux kernels wifi implementation. An attacker within wireless broadcast range can inject custom data into the wireless communication circumventing checks on the data. This can cause the frame to pass checks and be considered a valid frame of a different type.

A flaw was found in the Linux kernel's wifi implementation wherein an attacker within wireless range is able to abuse a logic flaw in the wifi implementation by reassembling packets from multiple fragments under different keys and they would be treated as valid. This allows an attacker to send a fragment under an incorrect key and be treated as a valid fragment under the new key.
