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.
|
|
If you already have a fix, please include it with your report, as
|
|
that can speed up the process considerably. 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.
|
|
|
|
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, though.
|
|
|
|
Non-disclosure agreements
|
|
-------------------------
|
|
|
|
The Linux kernel security team is not a formal body and therefore unable
|
|
to enter any non-disclosure agreements.
