Can we **please** stop discussing (suspected) security issue in this or 
any other public fora?

Apple needs to investigate this and while they do that we should not 
provide exploits or hints how to develop them.

If you are concerned please contact Apple.

Thank you.

In fact, before macOS 15.1, there was a serious issue with it, that broke long-running SSH connections. Maybe the DNS queries are tickling the firewall-related code and causing a kernel panic.
