First published: Tue May 11 2021(Updated: )
A vulnerability was found in Linux Kernel. Where the Wifi 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. Upstream patch: <a href="https://lore.kernel.org/linux-wireless/20210511180259.159598-1-johannes@sipsolutions.net/">https://lore.kernel.org/linux-wireless/20210511180259.159598-1-johannes@sipsolutions.net/</a>
