DeviceTree For Hackers: Intro

A leaked Raspberry Pi DeviceTree file reveals hardware details of the Pi Zero 3W, including a BCM2711 chip, PCIe support, a power button, an extra LED, and an eMMC option. This serves as the entry point for an intro to DeviceTree, the format that tells Linux kernels what CPU, drivers, and interfaces a board has. DeviceTree source files (.dts, .dtsi) compile into binary .dtb/.dtbo files the kernel reads, and the device-tree-compiler package handles both compiling and decompiling. The guide covers includes, base files, and overlays, recommends learning from Raspberry Pi's overlay directory and repos like Radxa and Armbian, and warns that LLMs sometimes hallucinate overlay properties.

sbom-cve-check 1.4.0 released

sbom-cve-check 1.4.0 has been released, adding an OpenVEX exporter and improving Linux kernel CVE analysis and version parsing. The new openvex export type, contributed by Andrey Zhizhikin, generates OpenVEX v0.2.0 documents with VEX assessments, configurable via a new --export-author option. Kernel CVE handling now distinguishes mainline versions like 6.12 from stable versions like 6.12.34 to reduce false positives and negatives. Version parsing also gained support for formats like 0.9~rc5 and Ubuntu-style suffixes, and build metadata like 1.25.0+4f85853f64 is now ignored per semver rules. Install or upgrade with pip install --upgrade "sbom-cve-check[extra]".
