CVE-2020-26146 is a Wi-Fi protocol/implementation flaw affecting WPA, WPA2, and WPA3 implementations that reassemble encrypted 802.11 fragments even when the fragments use non-consecutive packet numbers. The provided content specifically notes this behavior on Samsung Galaxy S3 i9305 4.4.4 devices and also references affected industrial wireless products such as Mitsubishi Electric GT25-WLAN and Siemens SCALANCE W-700 families. By accepting and reassembling encrypted fragments that should not be combined, the implementation violates expected packet-number consistency checks during fragment handling. An attacker can abuse this weakness to exfiltrate selected fragments under certain traffic conditions. This issue is part of the broader FragAttacks class of IEEE 802.11 fragmentation/aggregation weaknesses.
