CVE-2020-26139

CVE-2020-26139 affects NetBSD 7.1 kernel as described in connected documents. An Access Point forwards EAPOL frames to other clients before the sender has successfully authenticated, which may enable denial-of-service attacks against connected clients in Wi‑Fi networks and could facilitate exploi...

CVE-2020-26139

An issue was discovered in the kernel in NetBSD 7.1. An Access Point AP forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients an...

CVE-2020-26143

An issue was discovered in the ALFA Windows 10 driver 1030.36.604 for AWUS036ACH. The WEP, WPA, WPA2, and WPA3 implementations accept fragmented plaintext frames in a protected Wi-Fi network. An adversary can abuse this to inject arbitrary data frames independent of the network configuration...

CVE-2020-26143

CVE-2020-26143 describes a fragmentation/plaintext-frame acceptance vulnerability in wireless implementations that can allow packet injection within protected networks. Connected docs confirm the issue exists in multiple vendor advisories and disclosures related to FragAttacks, including Arista’s...

CVE-2020-26140

The CVE-2020-26140 entry is covered in ARISTA Security Advisory 0063, which groups it under the FragAttacks fragmentation/aggregation vulnerabilities. The advisory states that plaintext data frames are accepted on encrypted networks, enabling packet injection. Fixes are provided as platform-speci...

CVE-2020-24588

The 802.11 standard that underpins Wi-Fi Protected Access WPA, WPA2, and WPA3 and Wired Equivalent Privacy WEP doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated. Against devices that support receiving non-SSP A-MSDU frames which is mandatory as part of 802.11...

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...

UBUNTU-CVE-2020-26142

An issue was discovered in the kernel in OpenBSD 6.6. The WEP, WPA, WPA2, and WPA3 implementations treat fragmented frames as full frames. An adversary can abuse this to inject arbitrary network packets, independent of the network configuration...

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

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...
