CVE-2020-26147
A flaw was found in ieee80211rxhdefragment in net/mac80211/rx.c in the Linux Kernel's WiFi implementation. This vulnerability can be abused to inject packets or exfiltrate selected fragments when another device sends fragmented frames, and the WEP, CCMP, or GCMP data-confidentiality protocol is...
CVE-2020-26146
A vulnerability was found in Linux kernel, where the WiFi implementation 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...
CVE-2020-26143
A vulnerability was found in Linux kernel, where the WiFi implementations assemble 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...

Linux kernel input validation error vulnerability (CNVD-2021-34677)
Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel version 5.8.9. The vulnerability stems from when a device sends segmented frames and uses the WEP, CCMP, or GCMP data...
Nearly All Wi-Fi Devices Are Vulnerable to New FragAttacks
Three design and multiple implementation flaws have been disclosed in IEEE 802.11 technical standard that undergirds Wi-Fi, potentially enabling an adversary to take control over a system and plunder confidential data. Called FragAttacks short for FRgmentation and AGgregation Attacks, the...

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-2020-24586
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-2020-26144
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...
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...
