Bugs in operating system kernels can affect billions of devices and users all over the world. As a result, large body research has been focused on kernel fuzzing, i.e., automatically generating syscall (system call) sequences to detect potential bugs or vulnerabilities. Syzkaller, one most widely studied fuzzers, aims generate valid based predefined specifications written syzlang, domain-specific language for defining syscalls, their arguments, relationships between them. While there...
Abstract Additive manufacturing (AM) of copper through laser‐based processes poses challenges, primarily attributed to the high thermal conductivity and low laser absorptivity powder or wire as feedstock. Although use salts in vat photopolymerization‐based AM techniques has garnered recent attention, achieving micro‐architected with density remained elusive.

Leveraging deep learning (DL)-based code analysis tools to solve software engineering tasks is becoming increasingly popular. Code models often suffer performance degradation due various reasons (e.g., data shifts). Retraining required address these issues, but frequent model updates are costly in labeling and deployment. In this paper, we explore an alternative solution: Adapting the program inputs models. This can be achieved by two steps: 1) input validation that focuses on identifying...
