This note maps three runc container-escape CVEs disclosed together on November 5, 2025: the maskedPaths symlink bypass, the /dev/console mount race, and the LSM label write redirect. Chained they reach host root; patched individually they leave gaps for homelab distros.
Threat Intel
A second shadow-MMU escape in a month: Zapscape (CVE-2026-64561) lets a nested guest reach host root on an unpatched KVM. If you rebooted for Januscape, check the booted kernel again — separate bug, separate fix.

Five agencies published a joint PLC advisory. Its reconnaissance playbook works against a homelab with a public IP just as well as a PLC rack. A first-person external audit of the Malwlab surface: enumeration checklist, before/after delta, and controls left behind to catch anyone scanning back.

A five-day exploitation window, a reverse SSH backdoor, and a patch that closes the front door while the channel stays open. The vCenter triage.

CISA added four self-hosted apps to KEV in three weeks: Metabase, MLflow, Zimbra, Gitea. The 72-hour operator checklist: exposure check, patch or compensate, compromise check, scoped credential rotation, documentation for the next incident.
Threat Intel
Zimbra 10.1.x below 10.1.20 with the optional zimbra-snmp package and snmp_notify enabled is directly exploitable - CERT Polska confirms an ongoing in-the-wild campaign, the CISA KEV remediation due date has passed, and the observed persistence is JSP web shells in Jetty webapps.

Hands-on checklist for homelab operators: detect, fingerprint, and harden exposed MCP endpoints running on Ollama, Claude Code agents, or custom self-hosted AI services. Based on Trend Micro research documenting ~1,500 unauthenticated servers in 2026.

GreyNoise honeypot data reveals 300,000+ Ollama instances exposed to the internet. Bleeding Llama (CVE-2026-7482), LLMjacking campaigns, and agentic weaponization represent an escalating threat to homelab AI deployments.
