{"id":"CVE-2020-26146","details":"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.","aliases":["2860242","2874369","A-175626808","ASB-A-175626808"],"modified":"2026-03-15T14:06:34.290097Z","published":"2021-05-11T20:15:08.907Z","related":["ALSA-2021:4356"],"references":[{"type":"ADVISORY","url":"https://www.fragattacks.com"},{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2021/05/11/12"},{"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"}],"affected":[{"database_specific":{"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"}]},{"events":[{"introduced":"0"},{"fixed":"8.7.1.3"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-26146.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
