Astra Linux – Vulnerability in Linux

A 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 fully unfragmented frames. An adversary can exploit this vulnerability to inject arbitrary...

kernel: accepting fragmented plaintext frames in protected networks

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...

Internet Bug Bounty: Fragmentation and Aggregation Flaws in Wi-Fi

I discovered three design flaws in the Wi-Fi standard and widespread related implementation flaws see GitHub overview and test tool. Here I'll specifically cover open source software. These findings have not received bug bounties from other sources. Implementation flaws allowing trivial packet...

CVE-2020-26145

A flaw was found in ath10khttrxprocrxfragindhl in drivers/net/wireless/ath/ath10k/httrx.c in the Linux kernel WiFi implementations, where it accepts a second or subsequent broadcast fragments even when sent in plaintext and then process them as full unfragmented frames. The highest threat from th...

UBUNTU-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...
