Weekly Recap: Linux Flaws, Defender 0-Days, Router Botnets, and Supply Chain Chaos

The Hacker News weekly recap for late May 2026 synthesizes a turbulent week in cybersecurity dominated by multiple overlapping threat stories. Active exploitation of Linux kernel vulnerabilities — including the nine-year-old CVE-2026-46333 — alongside Microsoft Defender zero-days created urgent patching pressure for defenders. Router botnets continued to expand, ensnaring consumer and small business devices for massive DDoS campaigns. The supply chain attack landscape saw unprecedented activity with TeamPCP, TrapDoor, and Mini Shai-Hulud campaigns simultaneously compromising packages across npm, PyPI, and Packagist. The convergence of these threat streams created a particularly challenging week for SOC teams forced to triage between patching, supply chain auditing, and active threat response with limited resources.
