Embargoed hardware issues
|
||||
=========================
|
||||
|
||||
Scope
|
||||
-----
|
||||
|
||||
Hardware issues which result in security problems are a different category
|
||||
of security bugs than pure software bugs which only affect the Linux
|
||||
kernel.
|
||||
|
||||
Hardware issues like Meltdown, Spectre, L1TF etc. must be treated
|
||||
differently because they usually affect all Operating Systems ("OS") and
|
||||
therefore need coordination across different OS vendors, distributions,
|
||||
hardware vendors and other parties. For some of the issues, software
|
||||
mitigations can depend on microcode or firmware updates, which need further
|
||||
coordination.
|
||||
|
||||
.. _Contact:
|
||||
|
||||
Contact
|
||||
-------
|
||||
|
||||
The Linux kernel hardware security team is separate from the regular Linux
|
||||
kernel security team.
|
||||
|
||||
The team only handles the coordination of embargoed hardware security
|
||||
issues. Reports of pure software security bugs in the Linux kernel are not
|
||||
handled by this team and the reporter will be guided to contact the regular
|
||||
Linux kernel security team (:ref:`Documentation/admin-guide/
|
||||
<securitybugs>`) instead.
|
||||
|
||||
The team can be contacted by email at <hardware-security@kernel.org>. This
|
||||
is a private list of security officers who will help you to coordinate an
|
||||
issue according to our documented process.
|
||||
|
||||
The list is encrypted and email to the list can be sent by either PGP or
|
||||
S/MIME encrypted and must be signed with the reporter's PGP key or S/MIME
|
||||
certificate. The list's PGP key and S/MIME certificate are available from
|
||||
https://www.kernel.org/....
|
||||
|
||||
While hardware security issues are often handled by the affected hardware
|
||||
vendor, we welcome contact from researchers or individuals who have
|
||||
identified a potential hardware flaw.
|
||||
|
||||
Hardware security officers
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
The current team of hardware security officers:
|
||||
|
||||
- Linus Torvalds (Linux Foundation Fellow)
|
||||
- Greg Kroah-Hartman (Linux Foundation Fellow)
|
||||
- Thomas Gleixner (Linux Foundation Fellow)
|
||||
|
||||
Operation of mailing-lists
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
The encrypted mailing-lists which are used in our process are hosted on
|
||||
Linux Foundation's IT infrastructure. By providing this service Linux
|
||||
Foundation's director of IT Infrastructure security technically has the
|
||||
ability to access the embargoed information, but is obliged to
|
||||
confidentiality by his employment contract. Linux Foundation's director of
|
||||
IT Infrastructure security is also responsible for the kernel.org
|
||||
infrastructure.
|
||||
|
||||
The Linux Foundation's current director of IT Infrastructure security is
|
||||
Konstantin Ryabitsev.
|
||||
|
||||
|
||||
Non-disclosure agreements
|
||||
-------------------------
|
||||
|
||||
The Linux kernel hardware security team is not a formal body and therefore
|
||||
unable to enter into any non-disclosure agreements. The kernel community
|
||||
is aware of the sensitive nature of such issues and offers a Memorandum of
|
||||
Understanding instead.
|
||||
|
||||
|
||||
Memorandum of Understanding
|
||||
---------------------------
|
||||
|
||||
The Linux kernel community has a deep understanding of the requirement to
|
||||
keep hardware security issues under embargo for coordination between
|
||||
different OS vendors, distributors, hardware vendors and other parties.
|
||||
|
||||
The Linux kernel community has successfully handled hardware security
|
||||
issues in the past and has the necessary mechanisms in place to allow
|
||||
community compliant development under embargo restrictions.
|
||||
|
||||
The Linux kernel community has a dedicated hardware security team for
|
||||
initial contact, which oversees the process of handling such issues under
|
||||
embargo rules.
|
||||
|
||||
The hardware security team identifies the developers (domain experts) who
|
||||
will form the initial response team for a particular issue. The initial
|
||||
response team can bring in further developers (domain experts) to address
|
||||
the issue in the best technical way.
|
||||
|
||||
All involved developers pledge to adhere to the embargo rules and to keep
|
||||
the received information confidential. Violation of the pledge will lead to
|
||||
immediate exclusion from the current issue and removal from all related
|
||||
mailing-lists. In addition, the hardware security team will also exclude
|
||||
the offender from future issues. The impact of this consequence is a highly
|
||||
effective deterrent in our community. In case a violation happens the
|
||||
hardware security team will inform the involved parties immediately. If you
|
||||
or anyone becomes aware of a potential violation, please report it
|
||||
immediately to the Hardware security officers.
|
||||
|
||||
|
||||
Process
|
||||
^^^^^^^
|
||||
|
||||
Due to the globally distributed nature of Linux kernel development,
|
||||
face-to-face meetings are almost impossible to address hardware security
|
||||
issues. Phone conferences are hard to coordinate due to time zones and
|
||||
other factors and should be only used when absolutely necessary. Encrypted
|
||||
email has been proven to be the most effective and secure communication
|
||||
method for these types of issues.
|
||||
|
||||
Start of Disclosure
|
||||
"""""""""""""""""""
|
||||
|
||||
Disclosure starts by contacting the Linux kernel hardware security team by
|
||||
email. This initial contact should contain a description of the problem and
|
||||
a list of any known affected hardware. If your organization builds or
|
||||
distributes the affected hardware, we encourage you to also consider what
|
||||
other hardware could be affected.
|
||||
|
||||
The hardware security team will provide an incident-specific encrypted
|
||||
mailing-list which will be used for initial discussion with the reporter,
|
||||
further disclosure and coordination.
|
||||
|
||||
The hardware security team will provide the disclosing party a list of
|
||||
developers (domain experts) who should be informed initially about the
|
||||
issue after confirming with the developers that they will adhere to this
|
||||
Memorandum of Understanding and the documented process. These developers
|
||||
form the initial response team and will be responsible for handling the
|
||||
issue after initial contact. The hardware security team is supporting the
|
||||
response team, but is not necessarily involved in the mitigation
|
||||
development process.
|
||||
|
||||
While individual developers might be covered by a non-disclosure agreement
|
||||
via their employer, they cannot enter individual non-disclosure agreements
|
||||
in their role as Linux kernel developers. They will, however, agree to
|
||||
adhere to this documented process and the Memorandum of Understanding.
|
||||
|
||||
|
||||
Disclosure
|
||||
""""""""""
|
||||
|
||||
The disclosing party provides detailed information to the initial response
|
||||
team via the specific encrypted mailing-list.
|
||||
|
||||
From our experience the technical documentation of these issues is usually
|
||||
a sufficient starting point and further technical clarification is best
|
||||
done via email.
|
||||
|
||||
Mitigation development
|
||||
""""""""""""""""""""""
|
||||
|
||||
The initial response team sets up an encrypted mailing-list or repurposes
|
||||
an existing one if appropriate. The disclosing party should provide a list
|
||||
of contacts for all other parties who have already been, or should be
|
||||
informed about the issue. The response team contacts these parties so they
|
||||
can name experts who should be subscribed to the mailing-list.
|
||||
|
||||
Using a mailing-list is close to the normal Linux development process and
|
||||
has been successfully used in developing mitigations for various hardware
|
||||
security issues in the past.
|
||||
|
||||
The mailing-list operates in the same way as normal Linux development.
|
||||
Patches are posted, discussed and reviewed and if agreed on applied to a
|
||||
non-public git repository which is only accessible to the participating
|
||||
developers via a secure connection. The repository contains the main
|
||||
development branch against the mainline kernel and backport branches for
|
||||
stable kernel versions as necessary.
|
||||
|
||||
The initial response team will identify further experts from the Linux
|
||||
kernel developer community as needed and inform the disclosing party about
|
||||
their participation. Bringing in experts can happen at any time of the
|
||||
development process and often needs to be handled in a timely manner.
|
||||
|
||||
Coordinated release
|
||||
"""""""""""""""""""
|
||||
|
||||
The involved parties will negotiate the date and time where the embargo
|
||||
ends. At that point the prepared mitigations are integrated into the
|
||||
relevant kernel trees and published.
|
||||
|
||||
While we understand that hardware security issues need coordinated embargo
|
||||
time, the embargo time should be constrained to the minimum time which is
|
||||
required for all involved parties to develop, test and prepare the
|
||||
mitigations. Extending embargo time artificially to meet conference talk
|
||||
dates or other non-technical reasons is creating more work and burden for
|
||||
the involved developers and response teams as the patches need to be kept
|
||||
up to date in order to follow the ongoing upstream kernel development,
|
||||
which might create conflicting changes.
|
||||
|
||||
CVE assignment
|
||||
""""""""""""""
|
||||
|
||||
Neither the hardware security team nor the initial response team assign
|
||||
CVEs, nor are CVEs required for the development process. If CVEs are
|
||||
provided by the disclosing party they can be used for documentation
|
||||
purposes.
|
||||
|
||||
Process ambassadors
|
||||
-------------------
|
||||
|
||||
For assistance with this process we have established ambassadors in various
|
||||
organizations, who can answer questions about or provide guidance on the
|
||||
reporting process and further handling. Ambassadors are not involved in the
|
||||
disclosure of a particular issue, unless requested by a response team or by
|
||||
an involved disclosed party. The current ambassadors list:
|
||||
|
||||
============= ========================================================
|
||||
ARM
|
||||

|
||||

|
||||
|
||||

|
||||
============== ========================================================
|
||||
|
||||
If you want your organization to be added to the ambassadors list, please
|
||||
contact the hardware security team. The nominated ambassador has to
|
||||
understand and support our process fully and is ideally well connected in
|
||||
the Linux kernel community.
|
||||
|
||||
Encrypted mailing-lists
|
||||
-----------------------
|
||||
|
||||
We use encrypted mailing-lists for communication. The operating principle
|
||||
of these lists is that email sent to the list is encrypted either with the
|
||||
list's PGP key or with the list's S/MIME certificate. The mailing-list
|
||||
software decrypts the email and re-encrypts it individually for each
|
||||
subscriber with the subscriber's PGP key or S/MIME certificate. Details
|
||||
about the mailing-list software and the setup which is used to ensure the
|
||||
security of the lists and protection of the data can be found here:
|
||||
https://www.kernel.org/....
|
||||
|
||||
List keys
|
||||
^^^^^^^^^
|
||||
|
||||
For initial contact see :ref:`Contact`. For incident specific mailing-lists
|
||||
the key and S/MIME certificate are conveyed to the subscribers by email
|
||||
sent from the specific list.
|
||||
|
||||
Subscription to incident specific lists
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
Subscription is handled by the response teams. Disclosed parties who want
|
||||
to participate in the communication send a list of potential subscribers to
|
||||
the response team so the response team can validate subscription requests.
|
||||
|
||||
Each subscriber needs to send a subscription request to the response team
|
||||
by email. The email must be signed with the subscriber's PGP key or S/MIME
|
||||
certificate. If a PGP key is used, it must be available from a public key
|
||||
server and is ideally connected to the Linux kernel's PGP web of trust. See
|
||||
also: https://www.kernel.org/signature.html.
|
||||
|
||||
The response team verifies that the subscriber request is valid and adds
|
||||
the subscriber to the list. After subscription the subscriber will receive
|
||||
email from the mailing-list which is signed either with the list's PGP key
|
||||
or the list's S/MIME certificate. The subscriber's email client can extract
|
||||
the PGP key or the S/MIME certificate from the signature so the subscriber
|
||||
can send encrypted email to the list.
