Description
An issue was discovered in the kernel in OpenBSD 6.6. The WEP, WPA, WPA2, and WPA3 implementations treat fragmented frames as full frames. An adversary can abuse this to inject arbitrary network packets, independent of the network configuration.
A flaw was found in the Linux kernel, where the WiFi implementations treat fragmented frames as full frames. This flaw allows an attacker to inject arbitrary network packets independent of the network configuration. The highest threat from this vulnerability is to integrity.
