CVE-2020-26144: n/a vulnerability

CVE-2020-26144: 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 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.

Security readout for executives and security teams

This flaw lets a nearby Wi-Fi attacker inject network packets against a Samsung Galaxy S3 i9305 running Android 4.4.4 by abusing how it handles certain plaintext aggregated Wi-Fi frames. Sources do not provide a CVSS score, confirmed patch, or evidence of active exploitation. Exposure is most likely for organizations still operating Samsung Galaxy S3 i9305 devices on Android 4.4.4. Broader vendor advisories discuss related FragAttacks issues, but the supplied CVE text does not prove this specific CVE affects additional products. Treat this as a legacy-device exposure issue. It is not KEV-listed in the supplied data, but unsupported Wi-Fi clients can create avoidable packet-injection risk near corporate networks. Mitigation focus: Identify and retire Samsung Galaxy S3 i9305 Android 4.4.4 devices where possible.; Check Samsung or device-vendor guidance for firmware availability before relying on patching.; Restrict legacy Wi-Fi clients to isolated networks with limited internal access..
