{"id":"CVE-2020-26144","details":"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.","modified":"2026-03-15T22:35:12.684020Z","published":"2021-05-11T20:15:08.837Z","related":["ALSA-2021:4356"],"references":[{"type":"ADVISORY","url":"https://cert-portal.siemens.com/productcert/pdf/ssa-913875.pdf"},{"type":"ADVISORY","url":"https://github.com/vanhoefm/fragattacks/blob/master/SUMMARY.md"},{"type":"ADVISORY","url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wifi-faf-22epcEWu"},{"type":"ADVISORY","url":"https://www.arista.com/en/support/advisories-notices/security-advisories/12602-security-advisory-63"},{"type":"ADVISORY","url":"https://www.fragattacks.com"},{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2021/05/11/12"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-26144.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"4.4.4"}]},{"events":[{"introduced":"0"},{"fixed":"10.0.1-31"}]},{"events":[{"introduced":"0"},{"fixed":"10.0.1-31"}]},{"events":[{"introduced":"0"},{"fixed":"10.0.1-31"}]},{"events":[{"introduced":"0"},{"fixed":"10.0.1-31"}]},{"events":[{"introduced":"0"},{"fixed":"11.0.0-36"}]},{"events":[{"introduced":"0"},{"fixed":"11.0.0-36"}]},{"events":[{"introduced":"0"},{"fixed":"11.0.0-36"}]},{"events":[{"introduced":"0"},{"fixed":"11.0.0-36"}]},{"events":[{"introduced":"0"},{"fixed":"11.0.0-36"}]},{"events":[{"introduced":"0"},{"fixed":"11.0.0-36"}]},{"events":[{"introduced":"0"},{"fixed":"11.0.0-36"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
