Distros list statistics and data for 2026

Statistics by month

Statistics are grouped by month of the issue being reported to the private list.

Month All reports Embargoed Average Median Min Max embargo days
2026-01 3 3 7.42 6.81 1.28 14.15
2026-02 4 4 11.57 12.70 6.75 14.15
Total 7 7 9.79 11.74 1.28 14.15

Non-embargoed reports (issue already posted to oss-security before being brought to (linux-)distros, which in 2026 didn't occur yet) are (would be) excluded from the calculation of average, median, and minimum embargo duration above.

Formatted input data

For the statistics above, we only use the first embargo duration seen in this table, which is the delay between postings to (linux-)distros and oss-security.

For some reports, there's a second embargo duration - that one is the delay (sometimes negative) between a first public posting elsewhere and the posting to (linux-)distros. Such first public posting often does not fully (or at all) reveal security relevance of the issue/fix, making it not-too-unreasonable to allow a little bit (more) of embargo time on the full detail, especially when that's the issue reporter's and/or the upstream project's preference.

when the patches are published upstream in Linus's tree, in a few days and definitely before the maximum 14-day embargo
will almost certainly be published upstream in Linus's tree on Tuesday, March 10
wait until the patches appear in Linus's tree, even if the maximum 14-day embargo is slightly exceeded
