#1AI Is Breaking Two Vulnerability Cultures

Jeff Kaufman argues that AI is undermining both coordinated disclosure and Linux's "bugs are bugs" approach to security vulnerabilities. AI-assisted scanners can now identify security-relevant commits hidden among thousands of routine changes, and multiple AI groups independently rediscover embargoed vulnerabilities before patches ship. He advocates dramatically shorter embargo windows as AI accelerates both offense and defense.

#3You Gave Me a u32. I Gave You Root. (io_uring ZCRX Freelist LPE)

Security researcher ze3tar discloses an out-of-bounds heap write vulnerability in the Linux kernel's io_uring zero-copy receive (ZCRX) feature, affecting versions 6.15 through 6.19. The flaw exploits the freelist mechanism to corrupt heap memory using a small integer value, enabling local privilege escalation to root. The bug requires CONFIG_IO_URING_ZCRX=y but demonstrates how even small integer overflows in kernel subsystems can be weaponized.

#5An Introduction to Meshtastic

Meshtastic is an open-source project that turns inexpensive LoRa radios into long-range, off-grid mesh communication devices capable of encrypted text messaging without any cellular or internet infrastructure. The mesh architecture rebroadcasts messages to extend range, with a record distance of 331km. Primary use cases span emergency communication, remote-area connectivity, and off-grid messaging — an increasingly popular alternative to traditional networks.

#6My First In-Prod Corrupted Hard Drive Problem

A production SQL Server started failing backups due to a hard drive with weakly magnetized sectors, a problem exposed after a heavy I/O database patch. The author diagnosed the issue through a methodical process of eliminating EDR, VSS, and Windows system files before identifying the physical drive failure. They resolved it using HDD Regenerator to rewrite affected sectors, highlighting that backups alone don't guarantee data integrity.

#7Serving a Website on a Raspberry Pi Zero Running in RAM

A developer configured Alpine Linux on a Raspberry Pi Zero v1.3 to run entirely in RAM, using the 512MB microSD card only for boot and persistent storage. The setup uses the ultra-lightweight darkhttpd web server with TLS termination offloaded to an external VPS running HAProxy. The result is a fully functional, publicly accessible self-hosted website running diskless on one of the cheapest computers ever made.

The exhibition features playable versions of games from beloved series like Dexter's Laboratory, Powerpuff Girls, and other CN properties of that era. It's a nostalgia-fueled digital preservation effort that captures a lost chapter of browser-based gaming history.
