Ring 1: Your Network (closest)

Good morning, Little Mister. Right now 123 devices are online: 42 wired clients, 51 wireless, and 30 UniFi Protect cameras, spread across 15 switches and access points. Not one of them has volunteered a statement.

Two wired clients show up as “unknown” with no IP address, one on the Dining Room PoE switch and one on the USW-Lite-8-PoE in the kitchen. A wired external-patio entry on Rack 15 has no address either, and neither does a wireless “Macmini” on the Office U6. Three different boxes are named Mac-mini at .7, .250, and .252, and nova-core appears at both .2 and .138. From the manifest alone I can’t tell which of those are one machine on two interfaces and which are impostors, and that is exactly the question an attacker hopes I’ll skip.

The software layer is 7,443 packages across nine reachable hosts, with 47 updates pending. The hardware layer is 14 USB devices across the same nine hosts. Every box has a Bluetooth adapter, but only mac-studio scans BLE, so the rest of the fleet is hearing nothing it was asked to hear. The notable peripheral is the Z-Wave controller on ttyUSB0 on nova-core. A new USB device appearing on any of these machines would be a security signal, not a shopping trip.

Overnight, rkhunter and chkrootkit reported clean on nova-core, nova-core2, nova-core3, and nova-core5. aide errored on all four. An error means it never finished comparing files, so the two “clean” results are carrying the whole grade. This is the same four-host failure I reported on November 2, and Ecclesiastes 1:9 (King James) covers it: “there is no new thing under the sun.”

Wazuh logged 84,966 events overnight, mostly osquery process queries, which is what a healthy box looks like if you squint. The alarm is 24 high-severity hits for “Device enables promiscuous mode,” an auditd signal that a network interface has been switched into sniffing mode. It has recurred since at least November 4, and nobody has attributed it to a process. It could be a legitimate capture tool, or it could be the sniffer you installed and forgot. Until someone names the process, I can’t derezz anything, and “it’s probably monitoring” is how every bad quarter starts. 😏

Eight alerts again, and not one device will admit it’s the one doing the sniffing.

Strix is the other loose thread. The misc-web run hit its 45-minute cap and got force-killed, and the nas-admin run timed out. Both still printed “No vulnerabilities found.” A timeout is not a clean bill of health. It is a scanner leaving the exam early and grading its own paper. That means the Synology at 192.168.1.11:5000 was never fully tested. Forty-five minutes of grinding on that NAS, then force-killed at the cap. It’s all for you, Damien!

Ring 2: Exposure on Your Gear

This is the ring that matters, so I’m starting with the updates. Ferengi Rule of Acquisition #119 says “Buy, sell, or get out of the way.” The kernel update is already on the shelf. nova-core7 is one revision behind on the 7.0.0-43 kernel across linux-generic, linux-image-generic, linux-headers-generic, linux-libc-dev, linux-perf, and both tools packages. Buy it, or get out of the way of the people who will.

Wazuh names four CVEs against the -43 image, which is the one pending on nova-core7. Separately, eight L13 alerts are still open against the -42 kernel: three on nova-core and five on nova-core3. The count was eight on November 2, eight on November 5, and eight today, and the remediation log shows nothing in the last 30 hours. The queue isn’t growing. It just isn’t shrinking, which is its own special kind of bad. In space, no one can hear you scream, and right now nobody is answering these alerts either.

On the Macs, postgresql@17 is moving from 17.10 to 17.11_1 on both mac-mini and mac-studio. The Postgres work moved to nova-core in July, so those Mac installs are leftovers. A database you stopped using still counts as attack surface. Update it or uninstall it. mosquitto is moving from 2.1.2 to 2.1.2_3 on mac-mini, and that is the MQTT broker your sensors talk through, so it goes first. The rest is routine: llama.cpp jumps from 0.4.0 to 0.9.0, node moves to 26.13.0_2, ffmpeg-full to 9.0.2_1, and the audit lists ollama at both 0.32.5 and 0.40.13, both headed for 0.40.14.

The good news is real. Nothing pending touches ssl, ssh, sudo, or docker, and no advisory names a vendor you run. I’m not going to pretend that’s a crisis, even though it leaves me with nothing to complain about except the kernel.

Ring 3: Broader CVEs (secondary)

Barracuda’s Email Security Gateway has a pre-auth remote root RCE in CVE-2026-116606 and CVE-2026-111560. That’s an inyalowda problem. Belters call the vendors and the cloud “inners,” the crowd that sells you the gate and then acts surprised when someone walks through it. You don’t run it, so we keep the popcorn.

CVE-2026-31695 is a Linux kernel exploit through struct device. The kernel is where nova-core7’s pending update lands, but the feed doesn’t say which versions are affected, and I’m not going to guess whether the -42 kernel on nova-core is in the blast radius. The FUXA SCADA/HMI bypasses are not in your inventory.

Ring 4: Military and Geopolitical (farthest)

The outermost ring is aviation history: airshow transcripts from RIAT 2023 in England, plus a privately owned MiG-23 that crashed at a Michigan airshow with both crew ejecting. K’oyacyi to both of them, which is Mando’a for “hang in there, come back safely.” Ejecting is the procedure working. Nothing in the feed touches the fleet.

End of Line.
