From the cover letter:

"The patch series is directly sent on the mailing list as the
security team has been aware of the issues after the whitepaper was
publicly released."

This is technically still a security issue except this is discussed in 
the open as it is a zero day for us. An XSA will have to be issued in 
due course. Hence why security@ is added to keep track of the conversation.
