An adversary can abuse this to inject arbitrary network packets, independent of the network configuration.
MEDIUM 5.3EPSS 2.08%
Does this matter?
Lower severity and a low EPSS score (2.08%). Track it; it rarely justifies an emergency change on its own.
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.
