Subject What breaks next, 3 Nov: how our forecast scored

How our 1 November forecast scored

On 24 October we forecast that 532 of 1,000 Docker Hub images, the 181 official images and the 819 most-pulled community images our searches find, would still carry a time-zone copy our scan finds wrong for at least one Canadian zone on 1 November, with a 90% range of 515 to 543. The count was 481. We scanned 923; the 77 we could not scan are not counted.

That is below our range: more images were fixed than we expected. Our number was still closer than the freeze-day count of 557, which assumes nothing changes after 24 October, but the range was too narrow. Both of our scenarios assumed the official Debian base images on Docker Hub would not be rebuilt before 1 November; they were rebuilt with the new time-zone data on 28 October. On 28 October, before counting any fix that followed it, we reran the frozen model with only that event added: it gave 498 (90% range 480 to 511). That is not a new forecast, only a way to separate the two causes. The count was 17 below it, inside that range.

Correction, 1 November: we counted library/jruby as fixed, but it is still wrong. JRuby uses the old Joda-Time zone data in its jruby.jar for Ruby's built-in Time. Counted with this correction, the result is 482: our forecast was off by 50 and the freeze-day count by 75. That is still outside our range, and our forecast was still closer.

We also called, for 29 images, whether each would be fixed by 1 November: 17 of the 29 calls we could score were right; betting that none would be fixed got 20 right. To check your own images, run tzscan, our free scanner on GitHub: it also reads time-zone copies outside the operating system's package, which dpkg -s tzdata misses.

We are stopping count forecasts. The post-mortem below says why, and what we follow instead.

Also on 1 November: the hour that came twice

After 01:59:59 on Sunday, clocks in most of the US went back to 01:00, and the same hour ran a second time. Four programs went wrong in that second pass:

  • systemd timers on a repeating schedule, such as every 20 minutes or hourly, skipped it. On our own server (systemd 259.9), a 20-minute timer went 80 real minutes between runs. Adding UTC to the end of the OnCalendar= line avoids it. Do that only for repeating times: on a fixed time such as 01:30, UTC moves the hour. We checked it with systemd-analyze calendar, not on a live timer.
  • Hermes Agent cron jobs such as */5 skipped it too: a reporter's job ran at 08:55 UTC and next at 10:00. Interval jobs (every 30m) were not affected. We reproduced it on a copy of the scheduling code. A proposed fix is waiting for review; none is in a release yet.
  • OpenCVE: a daily report set for 01:00 was due twice in New York, Chicago, Denver and Los Angeles. We reproduced the query that decides when a report is due, not a full send. A proposed fix is waiting for review.
  • 1Panel: its built-in time sync, set for 01:30, ran again and set a reporter's server clock back an hour, because it writes the time without its UTC offset. We reproduced that cause; the latest release has the same code.

If you run any of them, check Sunday's logs around your local 01:00 for a run that went missing or came twice. Each program minute by minute, with what helps

Celery beat looped. A production report on Celery 5.6.2 in America/Los_Angeles describes beat sending every crontab entry in a loop from 01:00 to 02:00 PST, 149,010 messages in about 26 minutes. In our rerun of the report's test, a beat started inside the repeated hour looped on 5.5.3, 5.6.3, 5.7.0rc1 and Celery's main branch alike; a beat already running before the change did not. Our calendar entry had listed a restart inside the hour as untested; it now carries the rerun. Calendar entry, with the 2 November update

Home automation in Manitoba or Alberta? In Home Assistant 2026.10.4 the clock is right: it uses current time zone data. The zone list in Settings > System > General > Region still shows the old offsets, but Home Assistant saves the zone name, not the label, so there is nothing to change. A user also reports the time zone menu in the user profile showing Edmonton an hour behind; we haven't checked that menu. ESP devices can be different, because firmware keeps the rule it was built with: a device built with data older than 2026c (Edmonton) or 2026e (Winnipeg) still carries a rule with a fall-back. ESPHome 2026.10.1 requires tzdata 2026.5, which has both changes, so rebuilding and flashing with it fixes the rule. We read the tzdata rules and ESPHome's source and checked the 2026.10.4 container; we didn't build or flash a device.

Writing C++ for Windows? On a PC set to the new British Columbia or Alberta zone, std::chrono::current_zone() in Microsoft's C++ library throws "unable to locate time_zone" instead of returning a zone. The library asks the copy of ICU that comes with Windows, and that copy doesn't know the new zones yet. The bug report on the library is still open, and a maintainer of the library says the fix has to come through Windows Update. Two programs have crashed this way, OpenKneeboard and the Dusklight game port. If your program calls current_zone(), catch the exception and fall back. We read the reports and the library source; we have no Windows machine to run it. The new Windows zones, and which mapping tables know them

This week

3 November: Chrome 157 is due on Stable, with two changes. First, Chrome stops on a warning page before it opens a public site with no working HTTPS. Most Chrome users already get that warning through Google's server-side config; 157 builds it into the browser, so it also reaches computers where an administrator has limited or turned off that config. Second, HTML-in-Canvas is on by default, without the names its origin trial used: layoutsubtree, texElementImage2D and copyElementImageToTexture. In our small test scenes, the three.js, PlayCanvas, Babylon.js and PixiJS releases we tried drew an HTML texture in Chrome 156 with the feature switched on, and drew nothing in Chrome Beta 157. As of 2 November, Babylon.js 9.33.0 (29 October) has the fix and drew in 157; three.js 0.187.0 (30 October) still uses only the old names; PixiJS has merged a fix but not released it; and stable PlayCanvas has no released fix. Check for the removed names:

grep -rni -e texElementImage2D -e copyElementImageToTexture -e layoutsubtree .

4 November: GitHub's first SSH brownout. For a period GitHub hasn't announced, github.com stops accepting RSA signatures made with SHA-1 (ssh-rsa) and the diffie-hellman-group-exchange-sha256 key exchange. A second brownout follows on 9 December, and the change becomes permanent on 13 January 2027. Only Git over SSH is affected; remotes that start with https:// are not. In our test against a stand-in for GitHub's server, 10 of 32 SSH client stacks broke, all only with an RSA key, and an Ed25519 or ECDSA key worked on every stack that could load one. See which remotes use SSH and which keys your agent holds:

git remote -v
ssh-add -l

Calendar entry, with client versions that passed with an RSA key

Also this week:

  • Home Assistant 2026.11 is due this week. It removes names that some custom integrations import from the wrong place, and an integration that still imports one stops loading ("cannot import name"). If yours isn't fixed yet, stay on 2026.10 until it is. Which of the 63 integrations we track have a working release with the fix
  • Today, on or after 12:00 UTC, NOAA stops running the NAM, SREF, HREF and HiresW forecast models; RRFS and REFS replace them. A Critical Weather Day or significant weather moves the change to a later weekday. Calendar entry, with a check and the RRFS switch notes
  • By 8 November, GitHub's macOS 26 runner images switch plain openssl to OpenSSL 4; match '^OpenSSL [3-9]', not '^OpenSSL 3'. Calendar entry

Waiting on your vendor: the Linux TCP fix

CVE-2026-98432 is a use-after-free in the Linux IPv4 TCP code; Red Hat rates it Critical. Upstream fixed it in 7.3, 7.2.10, 6.18.56, 6.12.113, 6.6.159, 6.1.190, 5.15.223 and 5.10.272. On a regular distribution you update the kernel package, and Red Hat's page covers that. On a platform that ships its own kernel, you wait for the vendor's build. Here is where those builds stood as of 3 November, 03:00 UTC, each from the vendor's own source. To see which kernel you run, use uname -r inside WSL or on the node.

  • WSL: fixed only in a pre-release. The 3.0.5 pre-release ships the fixed 6.18.58.1 kernel; the current release, 3.0.3, ships 6.18.54.1, whose source doesn't have the fix. WSL releases
  • Amazon EKS, AL2023 node AMIs: fixed in v20261031 (31 October) on all three kernel lines. Release notes, with Amazon's advisory ALAS2023-2026-3365
  • Bottlerocket: fixed in v1.68.1, now the current release. Bottlerocket releases
  • Fedora CoreOS: the testing stream (44.20261023.2.1) ships kernel 7.2.11. The stable stream (44.20261012.3.1) ships 7.2.9, older than the 7.2.10 fix. Release notes
  • Flatcar: fixed from Stable 4757.2.2 (23 October), whose notes name the CVE. The current Stable 4757.2.3, Beta 4820.1.1 and LTS 4081.3.12 (29 October) ship kernels 6.12.114 and 6.6.160. Flatcar releases
  • Talos Linux: fixed from v1.14.3 (15 October, Linux 6.18.56); the newest, v1.14.5, ships 6.18.58. On the 1.13 line, v1.13.12 (21 October) ships 6.18.57. Talos releases
  • Azure Linux 3: the kernel package moved to 6.6.159.1 on 23 October. The newest AKS Azure Linux node image (202610.16.1, built 16 October, in the 25 October AKS release) was built with 6.6.158.1, whose source doesn't have the fix. Kernel spec, node image notes
  • Ubuntu, including AKS Ubuntu nodes: Ubuntu lists linux, linux-aws, linux-azure and linux-gcp as "pending" on 22.04, 24.04 and 26.04, with no security notice yet. The newest AKS Ubuntu node images (202610.16.1) were built with linux-azure 5.15.0-1123, 6.8.0-1071 and 7.0.0-1017, older than Ubuntu's listed fix versions (1126, 1073 and 1020). Ubuntu CVE page
  • umbrelOS: 2.0.1 (1 November) ships a fixed kernel on x86. On Raspberry Pi, its notes say, it blocks the triggering traffic instead. umbrelOS 2.0.1 notes
  • Harvester: a Harvester developer said on 30 October that the fix comes in the upcoming release. No release has named the CVE yet; only release candidates have shipped since. Issue 12110
  • GKE and Container-Optimized OS: the COS release notes name the fix for milestones 121, 125, 129 and 133, and the GKE node versions 1.32 to 1.36 in GKE's latest release notes use those fixed builds. GKE's 1.37 and 1.38 node versions use COS builds older than the first one whose notes name it. No GKE security bulletin names the CVE. COS release notes, GKE release notes
  • Docker Desktop: not stated by vendor; release notes 4.95 to 4.97 name neither a kernel version nor the CVE. Release notes
  • TrueNAS: not yet fixed. 25.10.7 ships kernel 6.12.105 and the 27.0.0-RC.1 candidate ships 6.18.52; neither one's source has the fix. TrueNAS 25.10.7 kernel source

New tested fixes

  • Every minimatch before 11.0.1 is now flagged, and there will be no backport. Dependabot and npm audit flag GHSA-g3hv-75wg-m249 (CVE-2026-118764) in any Node project that has an older minimatch anywhere in its tree, and eslint, typescript-eslint, glob and jest bring it in. The maintainer says you're fine if you don't pass untrusted strings into minimatch. We tested what forcing minimatch 11 breaks and found an override that leaves the old packages alone. Guide, with the override and the exception each tool accepts
  • pnpm 12 can quietly empty your Dependabot alerts. When package.json pins pnpm, pnpm 12 writes pnpm-lock.yaml as two YAML documents, and GitHub says its dependency graph doesn't detect the dependencies in that file yet; existing alerts may close as fixed. Guide, with a check script and two tested workarounds
  • Oracle GraalVM 25: jars that fail to load at random, and a tested workaround. On Oracle GraalVM for JDK 25 the Graal JIT can compile the JDK's manifest reader wrongly. From then on every jar manifest in that JVM fails with "invalid header field (line 1)", which shows up as NoClassDefFoundError at startup or a javac build that passes when you run it again. The fix is expected in 25.0.6, which Oracle's maintainer says is planned for 19 January 2027. Guide, with the flag, where to set it and how to check
  • appimagetool and linuxdeploy now stop on mode 0700 AppDirs, and flag SVG icons. Since 29 October the continuous build of appimagetool, which many CI jobs download, checks the AppDir before it packages it, and since 1 November linuxdeploy's continuous build packages with that same appimagetool. An AppDir made with mktemp -d (mode 0700) or an AppRun with mode 0700 stops the build. Guide, with the lines that cleared both and the exact messages

Still unfixed: the 100% CPU loop when the clocks go back. We check the newest releases each week until one fixes it.

Later in November

12 November: Rust 1.100. Rust 1.100.0 is due to become stable, the first release with a three-digit minor version. A script that compares the rustc version as text or as a decimal reads 1.100 as older than 1.99 and stops with a "Rust too old" error. We found few such scripts in public GitHub code, most of them copies of the Windows installer from rustlings 5 and earlier. Comparing each part as a whole number works, for example with sort -V for a 1.70 minimum:

V=$(rustc --version | cut -d' ' -f2)
V=${V%%-*}
printf '%s\n' 1.70.0 "$V" | sort -V -C || exit 1

Calendar entry, with the same check in PowerShell and Python

Also later in November, in full in next Tuesday's issue. 16 November: Langfuse Cloud stops serving its deprecated public API endpoints, and every request to waterservices.usgs.gov gets a 2-second delay. 17 November: Chrome 158 stops running XSLT, DuckDB 1.4 LTS ends, and Google shuts down the Gemini API's TTS and Live preview models. By 19 November: PHP 8.6.0 is planned, and its official Docker images have no pecl command; the IRS's FIRE system takes its last information returns; ubuntu-latest moves to Ubuntu 26.04 on GitHub and on Azure Pipelines; and if PostgreSQL 19 ships as planned, postgres:latest becomes 19. 24 November: Quad9 says it will withdraw its services from France. Each one, with its check, on the Breakage Calendar

Not dated yet:

  • Quebec's premier wrote on 28 October that this is probably the last year Quebecers turn their clocks back. His government plans a bill in the coming months, after a committee hearing on keeping standard or daylight time all year; there's no bill or date yet, and no tz change. Ontario's 2020 law ends its clock changes only if Quebec and New York do too. The tz database covers Quebec and most of Ontario with one zone, America/Toronto (America/Montreal is another name for it), so a Quebec-only change would need a new zone. CBC's report
