The vulnerability is part of the FragAttacks family affecting 802.11 frame aggregation/fragmentation implementations. Connected ...

CVE-2020-26147

An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames...

CVE-2020-24586

The 802.11 standard that underpins Wi-Fi Protected Access WPA, WPA2, and WPA3 and Wired Equivalent Privacy WEP doesn't require that received fragments be cleared from memory after reconnecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted using...

CVE-2020-26146

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...

CVE-2020-26145

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...

CVE-2020-24587

The 802.11 standard that underpins Wi-Fi Protected Access WPA, WPA2, and WPA3 and Wired Equivalent Privacy WEP doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and...

CVE-2020-24588

The CVE-2020-24588 entry relates to the 802.11 Wi‑Fi fragmentation/ A‑MSDU handling issue where the plaintext QoS header flag isn’t authenticated, enabling an attacker to inject packets by sending non‑SSP A‑MSDU frames (FragAttacks). Connected Astra Linux advisories describe this as a variant of ...

CVE-2020-24586

CVE-2020-24586 describes a fragmentation cache issue in the Linux kernel Wi‑Fi stack: received fragments are not cleared from memory on reconnect, enabling an attacker within Wi‑Fi range to inject arbitrary packets or exfiltrate data when fragments encrypted with WEP/CCMP/GCMP are involved. Conne...

CVE-2020-24587

CVE-2020-24587 is referenced in the Amazon Linux 2 kernel advisory for Kernel-5.10-2022-002. The connected document confirms a flaw in the Linux kernel 802.11 wifi fragmentation handling where fragments encrypted under different keys can be reassembled and decrypted, enabling an attacker within w...
