Anthropic pointed Claude Code at Linux kernel source files one at a time, framed as a security puzzle. It found a heap overflow in NFS code hiding since March 2003. Four more kernel bugs followed. 500+ validated vulnerabilities in weeks. Linux Foundation set aside $12.5M to help maintainers cope. Nobody found a volunteer to maintain a Google Drive library for 3.5 years. The bottleneck was never the bugs.

Anthropic pointed Claude Code at the #linux kernel source one file at a time, framed as a security puzzle. Found a heap overflow in NFS (Network File System) hiding since March 2003. Four more kernel bugs followed. 500+ validated vulnerabilities across open source in weeks.

Linux Foundation set aside $12.5M to help maintainers cope. Meanwhile, nobody could find one volunteer to maintain a Google Drive library for three and a half years. The bottleneck was never the bugs but the unpaid people.

An AI Agent Filed a DMCA Takedown. The Rights Holder Had No Idea.

An unauthorized AI agent filed a DMCA (Digital Millennium Copyright Act) copyright takedown against gallery-dl, and the rights holder never approved it. Linux 7.0-rc7 confirms April 13 stable release.

gallery-dl, an open source media downloader, got a DMCA takedown on GitHub filed through a third-party service. The CEO of the company whose copyrights were cited said an AI agent sent it "without our approval or permission."

The maintainer removed nine components. The project migrated to Codeberg. US law requires takedown notices under penalty of perjury. When an AI agent submits one autonomously, no one in the chain authorized the legal action.

📬 Linux 7.0's PostgreSQL Crisis, OpenClaw's Triple CVE, TigerFS

Linux 7.0-rc7 ships days before stable with PostgreSQL throughput halved on AWS Graviton4 and no fix in sight. OpenClaw collects three critical CVEs in three months. TigerFS mounts PostgreSQL as a filesystem for AI agents.

#Linux 7.0 removed a CPU scheduling mode #PostgreSQL (a widely deployed open source database) relied on for internal locking. Result: throughput on AWS Graviton4 (Amazon ARM servers) dropped to 49% of normal.

The kernel team says PostgreSQL should adopt RSEQ, a newer Linux API for safe lock restarts. PostgreSQL cannot ship that before Linux 7.0 goes stable mid-April.

Ubuntu 26.04 LTS ships April 23. LTS means five years. Teams on AWS ARM who upgrade will hit this silently.

📬 Open Source & Linux Weekly - W142026

European Commission loses 340 GB to supply chain attack, Linux doubles macOS on Steam at 5.33%, PHP ends 26 years of license confusion with a 51-0 BSD vote.

Greg Kroah-Hartman (Linux kernel maintainer) told The Register that AI bug reports stopped being garbage about a month ago, and nobody knows why. Torvalds noticed independently. Of 60 AI patches Kroah-Hartman reviewed, two-thirds were correct. Real reports, real fixes, systematic. Meanwhile, Linux crossed 5.33% on Steam, doubling macOS at 2.35%. The 3.10 point monthly jump is the largest in Steam survey history. SteamOS is the driver. #Linux #OpenSource
TeamPCP Trivy Compromise: European Commission AWS Breach Confirmed

CERT-EU confirms EC cloud breach via Trivy scanner. OpenClaw: 250K stars, 135K exposed. Sonatype: 454K malicious packages. 65% of CVEs have no severity score.

The European Commission ran Trivy, a security scanner, inside its automated build pipeline on AWS. A criminal group called TeamPCP poisoned Trivy itself.

The scanner had elevated permissions. Attackers used that access to steal 340 GB. ShinyHunters, a data extortion gang, published the dataset. 71 hosted clients affected.

Same attack hit Sportradar (23,169 athlete records, 328 API credential pairs offered for up to $50K) and 1,000+ other organizations.
