The Windows Registry Adventure #1: Introduction and research results

In a 20-month audit of the Windows Registry, Project Zero identified dozens of registry-specific bugs (resulting in ~50 CVEs, primarily Windows kernel elevation-of-privilege and information-disclosure issues), analyzed their root causes and exploitability, and developed proof-of-concept exploits for multiple flaws (including CVE-2022-34707 and CVE-2023-23420); Microsoft patched these issues under Project Zero's disclosure policy. The report highlights registry-specific exploitation primitives (e.g., hive memory corruption, out-of-bounds cell indexes), provides exploitability ratings (easy/moderate/hard) for findings, and promises deeper technical posts on techniques and case studies.
