CVSS 3.1
5.3 mediumCVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:NCVE-2020-26146
Medium (5.3). EPSS 5.6% chance of exploitation in the next 30 days.
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.
