CVSS: 5.3EPSS: 0%CPEs: 38EXPL: 0CVE-2020-26146 – kernel: reassembling encrypted fragments with non-consecutive packet numbers
https://notcve.org/view.php?id=CVE-2020-26146
11 May 2021 — 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. • http://www.openwall.com/lists/oss-security/2021/05/11/12 • CWE-20: Improper Input Validation CWE-307: Improper Restriction of Excessive Authentication Attempts •

https://notcve.org/view.php?id=CVE-2020-26145
11 May 2021 — An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets independent of the network configuration. Se detectó un problema en los dispositivos Samsung Galaxy S3 i9305 versión 4.4.4. Las implementaciones de WEP, WPA, WPA2 y WPA3 aceptan segundos fragmentos de transmisión ... • http://www.openwall.com/lists/oss-security/2021/05/11/12 • CWE-20: Improper Input Validation CWE-307: Improper Restriction of Excessive Authentication Attempts •

https://notcve.org/view.php?id=CVE-2020-26144
11 May 2021 — 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. Se detectó un problema en los dispositivos Samsung Galaxy S3 i9305 versión 4.4.4.
