CVE-2020-26146: An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices.

An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WPA, WPA2, and WPA3 implementations reassemble fragments with non-consecutive packet numbers. An adversary can abuse this to exfiltrate selected fragments. This vulnerability is exploitable when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. Note that WEP is vulnerable to this attack by design.

Security readout for executives and security teams

This is a Wi-Fi implementation flaw affecting Samsung Galaxy S3 i9305 4.4.4 devices. A nearby attacker may abuse mishandled fragmented wireless frames to expose selected fragments of traffic under specific conditions. The source bundle does not show internet exposure or active exploitation. Exposure is most likely in environments still using Samsung Galaxy S3 i9305 Android 4.4.4 devices or vendor-confirmed affected Wi-Fi products. The bundle does not prove broad exposure beyond listed references. Treat this as a moderate legacy wireless risk. Prioritize identifying obsolete devices and vendor-confirmed affected infrastructure, especially in sensitive networks, but do not treat it as an emergency without local exposure evidence. Mitigation focus: Check vendor advisories for firmware or security updates for CVE-2020-26146.; Retire or isolate legacy Galaxy S3 i9305 Android 4.4.4 devices.; Avoid WEP; it is described as vulnerable by design..
