1.. _securitybugs: 2 3Security bugs 4============= 5 6Linux kernel developers take security very seriously. As such, we'd 7like to know when a security bug is found so that it can be fixed and 8disclosed as quickly as possible. Please report security bugs to the 9Linux kernel security team. 10 11Contact 12------- 13 14The Linux kernel security team can be contacted by email at 15<security@kernel.org>. This is a private list of security officers 16who will help verify the bug report and develop and release a fix. 17If you already have a fix, please include it with your report, as 18that can speed up the process considerably. It is possible that the 19security team will bring in extra help from area maintainers to 20understand and fix the security vulnerability. 21 22As it is with any bug, the more information provided the easier it 23will be to diagnose and fix. Please review the procedure outlined in 24admin-guide/reporting-bugs.rst if you are unclear about what 25information is helpful. Any exploit code is very helpful and will not 26be released without consent from the reporter unless it has already been 27made public. 28 29Disclosure and embargoed information 30------------------------------------ 31 32The security list is not a disclosure channel. For that, see Coordination 33below. 34 35Once a robust fix has been developed, the release process starts. Fixes 36for publicly known bugs are released immediately. 37 38Although our preference is to release fixes for publicly undisclosed bugs 39as soon as they become available, this may be postponed at the request of 40the reporter or an affected party for up to 7 calendar days from the start 41of the release process, with an exceptional extension to 14 calendar days 42if it is agreed that the criticality of the bug requires more time. The 43only valid reason for deferring the publication of a fix is to accommodate 44the logistics of QA and large scale rollouts which require release 45coordination. 46 47While embargoed information may be shared with trusted individuals in 48order to develop a fix, such information will not be published alongside 49the fix or on any other disclosure channel without the permission of the 50reporter. This includes but is not limited to the original bug report 51and followup discussions (if any), exploits, CVE information or the 52identity of the reporter. 53 54In other words our only interest is in getting bugs fixed. All other 55information submitted to the security list and any followup discussions 56of the report are treated confidentially even after the embargo has been 57lifted, in perpetuity. 58 59Coordination with other groups 60------------------------------ 61 62The kernel security team strongly recommends that reporters of potential 63security issues NEVER contact the "linux-distros" mailing list until 64AFTER discussing it with the kernel security team. Do not Cc: both 65lists at once. You may contact the linux-distros mailing list after a 66fix has been agreed on and you fully understand the requirements that 67doing so will impose on you and the kernel community. 68 69The different lists have different goals and the linux-distros rules do 70not contribute to actually fixing any potential security problems. 71 72CVE assignment 73-------------- 74 75The security team does not assign CVEs, nor do we require them for 76reports or fixes, as this can needlessly complicate the process and may 77delay the bug handling. If a reporter wishes to have a CVE identifier 78assigned, they should find one by themselves, for example by contacting 79MITRE directly. However under no circumstances will a patch inclusion 80be delayed to wait for a CVE identifier to arrive. 81 82Non-disclosure agreements 83------------------------- 84 85The Linux kernel security team is not a formal body and therefore unable 86to enter any non-disclosure agreements. 87
