-Coordination
-------------
-
-Fixes for sensitive bugs, such as those that might lead to privilege
-escalations, may need to be coordinated with the private
-<linux-distros@vs.openwall.org> mailing list so that distribution vendors
-are well prepared to issue a fixed kernel upon public disclosure of the
-upstream fix. Distros will need some time to test the proposed patch and
-will generally request at least a few days of embargo, and vendor update
-publication prefers to happen Tuesday through Thursday. When appropriate,
-the security team can assist with this coordination, or the reporter can
-include linux-distros from the start. In this case, remember to prefix
-the email Subject line with "[vs]" as described in the linux-distros wiki:
-<http://oss-security.openwall.org/wiki/mailing-lists/distros#how-to-use-the-lists>
+Coordination with other groups
+------------------------------
+
+The kernel security team strongly recommends that reporters of potential
+security issues NEVER contact the "linux-distros" mailing list until
+AFTER discussing it with the kernel security team.  Do not Cc: both
+lists at once.  You may contact the linux-distros mailing list after a
+fix has been agreed on and you fully understand the requirements that
+doing so will impose on you and the kernel community.
+
+The different lists have different goals and the linux-distros rules do
+not contribute to actually fixing any potential security problems.
 
 CVE assignment
 --------------
 
-The security team does not normally assign CVEs, nor do we require them
-for reports or fixes, as this can needlessly complicate the process and
-may delay the bug handling. If a reporter wishes to have a CVE identifier
-assigned ahead of public disclosure, they will need to contact the private
-linux-distros list, described above. When such a CVE identifier is known
-before a patch is provided, it is desirable to mention it in the commit
-message if the reporter agrees.
+The security team does not assign CVEs, nor do we require them for
+reports or fixes, as this can needlessly complicate the process and may
+delay the bug handling.  If a reporter wishes to have a CVE identifier
+assigned, they should find one by themselves, for example by contacting
+MITRE directly.  However under no circumstances will a patch inclusion
+be delayed to wait for a CVE identifier to arrive.
