Name of the Vulnerable Software and Affected Versions ALFA Windows 10 driver version 6.1316.1209 Check Point GAiA affected versions not specified Description An issue was discovered in the Wi-Fi implementation of the ALFA Windows 10 driver, where it does not verify the Message Integrity Check of...

CVE-2020-24587: Use of a Broken or Risky Cryptographic Algorithm

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-2020-26140: Use of a Broken or Risky Cryptographic Algorithm

An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The WEP, WPA, WPA2, and WPA3 implementations accept plaintext frames in a protected Wi-Fi network. An adversary can abuse this to inject arbitrary data frames independent of the network configuration...

CVE-2020-26145: Improper Input Validation

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-2020-26147: Undefined Security Weakness

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-2020-26146: Improper Input Validation

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...

PT-2021-3060

Name of the Vulnerable Software and Affected Versions OpenBSD version 6.6 Description An issue was discovered in the kernel where the WEP, WPA, WPA2, and WPA3 implementations treat fragmented frames as full frames. This allows an adversary to inject arbitrary network packets, independent of the...

CVE-2020-26141: Improper Validation of Integrity Check Value

An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation does not verify the Message Integrity Check authenticity of fragmented TKIP frames. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the...

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-2020-24586: Undefined Security Weakness

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...
