I found a vulnerability in OpenVPN’s Windows kernel driver involving a use-after-free / double-free condition, resulting in a reproducible BSOD. I built a working PoC and reported the issue to the OpenVPN team. Currently waiting for a fix before sharing technical details. #openvpn #bsod #uaf #research #vulnerable #kernel

qwerty and I exploited a VSock 1-day in Google kernelCTF back in *February*, securing $71,337 🥳 (CVE-2025-21756, exp237/exp249) And I’ve just published the write-up: A kernel developer reviewing a patch for a separate VSock bug I submitted accidentally discovered this vulnerability, and we were the first to exploit it. PoC 💻: root on Ubuntu 24.04

Excited to share the KDA: Kernel Design Agents that powers HAN Lab Kernel Mafia top ranking #1~3 kernels at Kernel Contest🚀🚀🚀 Thanks to agents, everyone can be a "kernel bro" in 2026: By adapting the KDA, the team ranked #1 in MoE, #2 in DSA, and #3 in GDN in the Pure Agent track at MLSys FlashInfer Kernel Contest – especially given the fact that the main participant (dongyun zou) has only written ~400 LoC triton and 0 lines of CUDA in 2026. The core philosophy here is to leverage Humanize (the best harness framework) to let the agent run autonomously for as long as possible. By minimizing human involvement and input, and placing full trust in the agent, we can achieve kernel performance that nears SOTA levels.

Southern California firefighters race to free a driver trapped underneath a loaded tractor-trailer after a crash on Interstate 10. Dramatic footage from the San Bernardino County Fire Department shows crews working around the crushed sedan in Fontana Saturday morning. Officials say the driver remained "awake and responsive" while trapped before crews successfully extricated the motorist and rushed them to a local trauma center for treatment.

I accidentally stumbled on a GitHub repo list that VPN companies LEFT PUBLIC. Downloaded it before they noticed. What I found inside explains EVERYTHING about how to bypass restrictions WITHOUT paying $10/month. Here are 9 VPN repos worth bookmarking: ↳ ⭐ 23.5k | Streisand. Self-hosted VPN with WireGuard, OpenVPN, Tor. ↳ ⭐ 21.7k | Hysteria. Fast censorship-resistant proxy. ↳ ⭐ 21.2k | NekoBox for Android. Universal proxy toolchain. ↳ ⭐ 40.7k | Free VPN nodes (v2ray/trojan/shadowsocks) ↳ ⭐ 34.1k | V2fly v2ray-core. Build proxies to bypass restrictions. ↳ ⭐ 33.5k | XX-Net. Proxy tool to bypass GFW. ↳ ⭐ 20.6k | OpenVPN installer for Ubuntu, Debian, Fedora. ↳ ⭐ 15.7k | Lantern open-source VPN. Android iOS Windows macOS. ↳ ⭐ 15.1k | Brook. Cross-platform programmable network tool.

PSA: Do not open your windows in Waymos. I was assaulted and robbed in a Waymo in the Mission District. I was punched three times in the face and head. Waymo treats criminals as pedestrians and stops moving, leaving you vulnerable. They gave me 5 free rides tho

Most people use Linux every day. But Very few understand what actually happens after they press the power button. >>>Here’s the sequences Linux goes through before you get the login screen. Power button pressed → BIOS or UEFI initializes hardware and runs POST. Firmware locates the bootloader from disk. Bootloader loads the Linux kernel and initramfs into RAM. Kernel decompresses and takes control of the CPU. Memory management and the scheduler are initialized. Device drivers load to communicate with hardware. Temporary root filesystem mounts from initramfs. PID 1 starts as systemd and userspace begins. System services and daemons start in order. Login prompt or GUI becomes available. You run a command and it becomes a process with a PID. Process runs in user mode with limited privileges. When hardware access is needed, a system call is made. CPU switches from user mode to kernel mode. Kernel validates the request and executes through drivers. Result is returned back to user space. Scheduler continuously allocates CPU time across processes. Virtual memory isolates and protects processes. Filesystem manages data abstraction over storage. Network stack processes packets inside the kernel. Linux is the kernel coordinating hardware, processes, memory, and security through strict privilege control.

Even with close confirmation I sometimes close my terminal and think "OH FUCK NO." Coming soon to Ghostty, you can undo that. 🥰 (Technical details: we keep the terminal running for a configurable time in the background before terminating for real, similar to email undo send). (macOS only for now, AppKit APIs provide a nice undo manager implementation that eases this quite a bit. I still have to do research on GTK for Linux.)

⚠KNOWN ISSUE⚠ In todays update, the procedure to hide the character from only the local player no longer works. I am trying to apply a temp patch to restore functionality while I research ways to fully fix this issue. Thank you oogghii for bringing this to my attention!

I found a component library with 250+ animations that will make your frontend look insane. And it's completely FREE ! >Ready to use components with animations built in >Copy and drop straight into your project >The kind of UI that makes your app look like a $50K build Your frontend will never look the same.

The Phillies will use an opener before Taijuan Walker in his next outing. After some tweaks to his routine didn’t fix his first-inning issues, it’s “trial and error” as the team tries to find a solution.
