About this tag
Fuzzing is a software testing technique that involves feeding random or malformed data into an application to uncover vulnerabilities. On WindowsForum.com, discussions cover fuzzing in the context of Linux kernel hardening, Hyper-V virtualization security, and Microsoft Office file format bugs. Topics include the use of fuzzing tools like syzbot to find kernel flaws, fuzzing para-virtualized devices in Hyper-V, and how hackers have used fuzzing to exploit Office file parsing code. These threads highlight fuzzing as a critical method for identifying security weaknesses in operating systems, hypervisors, and enterprise applications, often leading to patches and improved input validation.
