An experimental Linux driver has been developed for the Fairphone 6's ultra-wide camera, enabling QR scanning capability on mainline Linux via the qcom-camss driver and libcamera.
432 Linux kernel CVEs were published in the last 24 hours, indicating a significant batch of security vulnerabilities.
Introduces pve-microvm, a Debian package that integrates QEMU's microvm machine type into Proxmox VE, enabling sub-300ms boot times and hardware isolation with minimal overhead, supporting various guest OS types.
A filtering engine and database that scans public kernel commits to identify security patches that have not yet been propagated to stable branches, helping developers track potential vulnerabilities.
LiteTopK is a fused indexer-top-k kernel for long-context sparse attention that exploits the curse of dimensionality to reduce memory traffic and improve efficiency, accelerating GLM 5.2 by 1.2x during prefill.
A modern Rust rewrite of the Linux 0.11 kernel that boots in QEMU on i386, featuring a full userland with shell and coreutils, with one-command image building and devcontainer support.
This article describes how researchers at Praetorian used Claude Opus (via Claude Code) to discover and exploit vulnerabilities in the FreeBSD kernel, including a stack overflow (CVE-2026-3038) that allows escape from FreeBSD jails. Part one focuses on methodology for finding bugs.
A developer shares their day 6 of inference engineering, writing a CUDA kernel for 1D convolution, explaining PagedAttention's memory efficiency, and providing an overview of GPU memory hierarchy (global, register, local, constant, shared).
This article provides a detailed walkthrough of what happens when a CUDA kernel is compiled and executed on an NVIDIA GPU, covering compilation to PTX and SASS, and the underlying hardware interaction.
AI tool VEGA from Nebula Security discovered a 15-year-old use-after-free bug in the Linux kernel (GhostLock) that allows any logged-in user to gain root access. The flaw, present since 2011, was patched in April but rollout is uneven.
Tweet recommending a blog post that explains the CPU-GPU communication details required when launching a CUDA kernel.
GhostLock (CVE-2026-43499) is a 15-year-old Linux kernel 0-day used in the IonStack full chain exploit, affecting all Linux devices from IoT to desktops. Nebu Security won a $92,337 bug bounty and published the exploit on GitHub.
Linux 7.0 removed the PREEMPT_NONE kernel preemption mode, causing a PostgreSQL benchmark regression in specific configurations, but most users will not notice the change.
Hugging Face introduces major updates to its Kernels project, including a new repository type on the Hub, improved security with trusted publishers and kernel signing, revamped CLIs, expanded framework/backend support, and a foundation for agentic kernel development.
Since Linux 6.9, LUKS suspend stopped wiping disk-encryption keys from memory, potentially exposing them to attackers.
A detailed technical walkthrough of the process from compiling a CUDA kernel to its execution on an RTX 4090, covering the NVCC compilation pipeline, PTX, SASS, and the underlying system calls.
LeetCUDA is an open-source CUDA system tutorial on GitHub, featuring over 200 progressive CUDA Kernel practice problems and 100+ high-performance computing blog posts. Its companion HGEMM library achieves 98%–100% of cuBLAS performance, making it ideal for CUDA beginners and AI engineers to systematically master CUDA optimization.
A detailed technical article explaining the Linux kernel scheduler, including task_struct, scheduling classes, context switching, and the EEVDF algorithm.
Yuri Zaporozhets of QRV Systems has built a RISC-V-based personal computer and a mainframe on an FPGA, and rewritten QNX twice. His latest OS QSOE is gaining attention in the FOSS world.
The Linux kernel has finally removed the dangerous strncpy function after six years and over 360 patches, replacing it with safer alternatives like strscpy that guarantee NULL-termination.
