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 +:doc:`reporting-bugs` 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. + +Please send plain text emails without attachments where possible. +It is much harder to have a context-quoted discussion about a complex +issue if all the details are hidden away in attachments. Think of it like a +:doc:`regular patch submission <../process/submitting-patches>` +(even if you don't have a patch yet): describe the problem and impact, list +reproduction steps, and follow it with a proposed fix, all in plain text. + +Disclosure and embargoed information +------------------------------------ + +The security list is not a disclosure channel. For that, see Coordination +below. + +Once a robust fix has been developed, the release process starts. Fixes +for publicly known bugs are released immediately. + +Although our preference is to release fixes for publicly undisclosed bugs +as soon as they become available, this may be postponed at the request of +the reporter or an affected party for up to 7 calendar days from the start +of the release process, with an exceptional extension to 14 calendar days +if it is agreed that the criticality of the bug requires more time. The +only valid reason for deferring the publication of a fix is to accommodate +the logistics of QA and large scale rollouts which require release +coordination. + +While embargoed information may be shared with trusted individuals in +order to develop a fix, such information will not be published alongside +the fix or on any other disclosure channel without the permission of the +reporter. This includes but is not limited to the original bug report +and followup discussions (if any), exploits, CVE information or the +identity of the reporter. + +In other words our only interest is in getting bugs fixed. All other +information submitted to the security list and any followup discussions +of the report are treated confidentially even after the embargo has been +lifted, in perpetuity. + +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 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. + +Non-disclosure agreements +------------------------- + +The Linux kernel security team is not a formal body and therefore unable +to enter any non-disclosure agreements. |
