Drupal patches two critical RCE flaws, warns exploits may emerge soon

IT & infrastructure

Kernel and platform maintenance dominated. Linux bug-fix volume has doubled, Chrome and Edge are dropping XSLT, and an AI-written clustered filesystem has appeared.

What happened

• LWN reports that bugs fixed per Linux kernel release have more than doubled since April 2026. Hacker News (front page) ↗

• Chrome and Edge are removing XSLT support. The linked article sets out which web uses will break and which will not. Check any XML feeds or sites that render through client-side XSLT. Hacker News (front page) ↗

• MeshXFS is an open-source clustered filesystem adapted from XFS by Claude Opus with no human-written code, per Phoronix. The summary says nothing about maturity or testing. Phoronix ↗

• Pending Linux VirtIO-FS code that enables synchronous queues shows significant performance gains for host-guest file sharing. Phoronix ↗

• Linux 7.4 previews include Radeon HDMI 2.1 enabled by default, AMD PerfOpt and Apple M4 support. Phoronix ↗

• ReactOS's NTFS driver is now mature enough to install and run ReactOS on NTFS, and NTFS formatting support has been added. Phoronix ↗

  Feed excerpt

  MeshXFS is a clustered open-source file-system in which "no human wrote any of its own code". Depending upon your views of AI, not necessarily something you want to hear for entrusting your data in an AI-created solution. Instead, Claude Opus was tasked with adapting the XFS file-system driver into a clustered file-system...

• Show HN: Esp32sim – Run ESP32 firmware in the browser3

  Esp32sim is an open-source browser-based ESP32 emulator that runs firmware without physical hardware, seeking embedded developer feedback.

  Hi HN, I’ve been working on esp32sim, an open-source ESP32 emulator that runs in the browser. The fun part of the demo is that there is no ESP32 involved — the firmware is executing in the emulator. The goal is to make ESP32 software easier to experiment with, test and simulate without always needing physical hardware connected. Source: https://github.com/mikroverk/esp32sim I made a short video showing it in action: https://youtu.be/waoWFilTWEc I’m particularly interested in feedback from embedded developers: what would an emulator like this need to support before you’d actually use it for development, testing or CI?
