6,232Auf GitHub ansehenSyzkaller is an unsupervised, coverage-guided kernel fuzzer that automatically generates and mutates system call sequences to find bugs in operating system kernels. It operates without human intervention, using a closed feedback loop of input generation, execution, crash detection, and corpus refinement to continuously explore kernel code paths. The fuzzer distinguishes itself by supporting multiple operating system kernels, including Linux, FreeBSD, and Windows, through per-platform syscall harnesses that abstract system call interfaces behind a common driver. It uses declarative description
Distributed, coverage-guided fuzzer for Linux kernel syscalls.

dvyukov/go-fuzz
4,853Auf GitHub ansehengo-fuzz is a coverage-guided randomized testing tool for identifying crashes and logic bugs in Go code. It consists of a fuzzer that evolves random inputs based on code execution paths, an instrumentation tool that produces binaries for tracking coverage, and a seed corpus manager. The tool utilizes compile-time binary instrumentation to monitor branch coverage and employs a feedback-driven mutation loop to prioritize inputs that reach new sections of the codebase. It includes capabilities for comparative differential testing to identify logic errors by executing different implementations of
Coverage-guided testing tool for Go packages.

4,362Auf GitHub ansehenThis is a public archive of vulnerability findings, proof-of-concept code, and technical reports detailing security flaws discovered in third-party software. It functions as a coordinated vulnerability disclosure platform, enabling private reporting to vendors and structured publication of advisories after a fix is released or a 90-day deadline passes. The repository provides modular security analysis tooling—standalone scripts and binaries each targeting a specific bug class for automated detection—alongside a cross-platform fuzzing framework that runs tests across multiple operating systems
Runs fuzz tests across multiple operating systems and architectures to uncover software defects.
