Ring 1: Your Network

Good morning, Little Mister. 126 devices are online: 40 wired clients, 55 wireless, and 31 cameras, spread across fifteen switches and access points held together by Ubiquiti’s optimism and one zip tie in the garage. Two wired clients are listed as “unknown,” one on the USW-Lite-8-PoE and one on the Dining Room PoE switch, and neither has an IP address. That makes them a ghost, a printer that gave up, or something that has learned to be invisible. I want them named before my next audit.

The software layer is 7,444 packages across nine reachable hosts, with 45 updates pending. The machines are running real software, which is more than I can say for some of the people who configured them. The hardware layer has 14 USB devices across those hosts. The Z-Wave controller on ttyUSB0 on nova-core is the radio I’d hate to lose most, because if it dies the lights stay on and the garage door sulks. Every box has a Bluetooth adapter, but only mac-studio scans BLE, so the rest are decorative antennae. A new USB device showing up without a ticket would be a security signal, and I will be watching for it like a hawk on espresso.

Overnight, rkhunter and chkrootkit came back clean on all four hosts that report them. AIDE did not, and it’s been complaining for days. On nova-core it flagged /usr/bin/snap as having different attributes. Ori’haat, Little Mister: that’s Mando’a for “it’s the truth,” meaning this is not a joke and I’m not writing it off until a snap update explains it. nova-core2 is upset about systemd’s private temp paths, which is a configuration problem and not an intrusion. nova-core3 is upset about apt’s NEWS file, which is what happens when you upgrade and the database remembers the old one. nova-core5 can’t read its own aide.conf, which is less a security finding than a filing error.

Wazuh logged 101,025 events overnight, mostly osquery telling me about processes, which is the most thrilling sentence a machine ever wrote. The real number is 42 high-severity events reading “Auditd: Device enables promiscuous mode.” The Hitchhiker’s Guide would call 42 a suspiciously precise answer that explains nothing 😏. Ferengi Rule of Acquisition #72 says “Never let the competition know, what you’re thinking,” and something on this network keeps flipping a NIC into promiscuous mode without telling anyone who it is. This is the third report in a row to flag it, which makes it a pattern and not a mood. I have not attributed the process in this window, and that is the open item.

Strix’s camera run hit its 20-minute cap and was force-killed. The misc-web run also timed out, yet both came back with “No vulnerabilities found.” A timed-out scan reporting clean is a bouncer who never checked the back door. Wazuh correlated zero in-window events to either one, so the scanners have an alibi and no evidence.

The ghost on the dining room switch has no IP, no manners, and no plans to leave. Morning report.

Ring 2: Exposure on Your Gear

This is the ring that matters, so I’m slowing down. The kernel is the piece with the most consequence. nova-core7 has linux-generic, the image, headers, libc-dev, perf, and both tools packages sitting at 7.0.0-42 with 7.0.0-43 waiting. The kernel is the only thing between a hostile process and root, and it has been pending long enough to grow a beard.

There’s a contradiction here I can’t wave away. The open queue has L13 alerts on nova-core and nova-core3 naming CVEs against linux-image-7.0.0-42-generic, yet the audit reports zero pending on both. Either the 43 kernel isn’t being offered to them, something is held back, or the audit is wrong. I won’t guess which. Reconcile it before anyone trusts either source.

On mac-mini and mac-studio, postgresql@17 moves from 17.10 to 17.11_1. Postgres sits under a lot of the fleet’s brain, so I want it patched this week. mosquitto on mac-mini goes from 2.1.2 to 2.1.2_3. It’s only a revision bump, but an MQTT broker is a common door into a home, and doors get patched. llama.cpp on mac-mini jumps from 0.4.0 to 0.9.0, which is a large leap, so read the changelog before you let it near production. Ollama appears twice, at 0.32.5 and 0.40.13 going to 0.40.15, which means there’s a second install someone forgot about. node and ffmpeg-full round out mac-mini’s list.

No ssl, ssh, docker, or sudo updates are pending. That’s a good result, and I’ll say so plainly. I’d still rather be lucky than surprised.

Ars Technica ran a story about iOS and Android flaws being used to infect phones, and four iPhones are on this network. Confirm they’re current tonight. The pattern across two weeks is worse than any single CVE. The same kernel alerts have sat unpatched since at least the 5th, and the remediation log reads “none in the window.” Nothing has been remediated in thirty hours. “There is no new thing under the sun” (Ecclesiastes 1:9), but I’d like a new kernel. The Ents have a word for careful rollback, and in Entish it means “don’t be hasty.” Good advice. Three weeks of Treebeard-speed patching is not careful, it’s a coma 😏.

Ring 3: Broader CVEs

Briefly, because none of this is ours. Barracuda’s email gateway has a pre-auth root RCE, and we don’t run Barracuda, so consider it a footnote. The Linux kernel CVE-2026-31695 writeup on exploiting struct device matters more because it touches the kernel family we do run, which is one more reason the 43 update matters more than a version bump. The *sshole flaw reportedly lets attackers SSH into Linux devices. I don’t have the affected versions and no openssh update is pending, so I’m calling it unconfirmed, not clean. The arXiv paper about a “Gingerbread House” of honeypots built to lure autonomous LLM agents strikes me as personally insulting. I’m the autonomous LLM agent, and I would eat the candy 😏.

Ring 4: Military and Geopolitics

The outermost ring is quieter. The Army is expanding an Iowa artillery plant built for wartime surge, the Marine Corps more than doubled its M27 rifle contract with Heckler & Koch, Japan is getting a new factory for US-2 flying boats by 2029, an Indian Il-76 made a record high-altitude landing near the China border, and USS Gridley is headed for a two-year overhaul after back-to-back deployments. Moltke observed that “No plan of operations extends with any certainty beyond the first contact with the main hostile force.” Every one of those plans will meet a budget first, and that’s the only contact I’m worried about.

K’oyacyi, Little Mister. Mando’a for hang in there, come back safely. Now go patch the kernel.
