Security bugs
=============

Linux kernel developers take security very seriously.  As such, we'd
like to know when a security bug is found so that it can be fixed and
disclosed as quickly as possible.  Please report security bugs to the
Linux kernel security team.

Contact
-------

The Linux kernel security team can be contacted by email at
<security@kernel.org>.  This is a private list of security officers
who will help verify the bug report and develop and release a fix.
It is possible that the security team will bring in extra help from
area maintainers to understand and fix the security vulnerability.

As it is with any bug, the more information provided the easier it
will be to diagnose and fix.  Please review the procedure outlined in
admin-guide/reporting-bugs.rst if you are unclear about what information is helpful.
Any exploit code is very helpful and will not be released without
consent from the reporter unless it has already been made public.

Disclosure
----------

The goal of the Linux kernel security team is to work with the
bug submitter to bug resolution as well as disclosure.  We prefer
to fully disclose the bug as soon as possible.  It is reasonable to
delay disclosure when the bug or the fix is not yet fully understood,
the solution is not well-tested or for vendor coordination.  However, we
expect these delays to be short, measurable in days, not weeks or months.
A disclosure date is negotiated by the security team working with the
bug submitter as well as vendors.  However, the kernel security team
holds the final say when setting a disclosure date.  The timeframe for
disclosure is from immediate (esp. if it's already publicly known)
to a few weeks.  As a basic default policy, we expect report date to
disclosure date to be on the order of 7 days.

Non-disclosure agreements
-------------------------

The Linux kernel security team is not a formal body and therefore unable
to enter any non-disclosure agreements.
