CVE-2020-24588 (GCVE-0-2020-24588)
Vulnerability from cvelistv5 – Published: 2021-05-11 00:00 – Updated: 2026-04-14 08:48
VLAI?
EPSS
Summary
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 802.11n), an adversary can abuse this to inject arbitrary network packets.
Severity ?
No CVSS data available.

VLAI?
EPSS
Summary
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 the WEP, CCMP, or GCMP encryption key is periodically renewed.
Severity ?
No CVSS data available.

CVE-2020-26147 (GCVE-0-2020-26147)
Vulnerability from cvelistv5 – Published: 2021-05-11 19:40 – Updated: 2026-04-14 09:01
VLAI?
EPSS
Summary
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 and the WEP, CCMP, or GCMP data-confidentiality protocol is used.
Severity ?
No CVSS data available.

CVE-2020-26144 (GCVE-0-2020-26144)
Vulnerability from cvelistv5 – Published: 2021-05-11 19:33 – Updated: 2026-04-14 08:49
VLAI?
EPSS
Summary
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.
Severity ?
No CVSS data available.

Summary
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 independent of the network configuration.

CVE-2020-24586 (GCVE-0-2020-24586)
Vulnerability from cvelistv5 – Published: 2021-05-11 00:00 – Updated: 2024-08-04 15:19
VLAI?
EPSS
Summary
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 (re)connecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.
Severity ?
No CVSS data available.

CVE-2020-26139 (GCVE-0-2020-26139)
Vulnerability from cvelistv5 – Published: 2021-05-11 19:37 – Updated: 2026-04-14 08:49
VLAI?
EPSS
Summary
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 and makes it easier to exploit other vulnerabilities in connected clients.
Severity ?
No CVSS data available.

CVE-2020-26146 (GCVE-0-2020-26146)
Vulnerability from cvelistv5 – Published: 2021-05-11 19:39 – Updated: 2026-04-14 08:49
VLAI?
EPSS
Summary
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.
Severity ?
No CVSS data available.
