Summary:
- This article discusses a new fuzzing technique called "Hexagon Fuzz" that can be used to find vulnerabilities in Qualcomm's baseband processors, which are the chips that handle cellular communication in many smartphones.
- Hexagon Fuzz is a full-system emulated fuzzing approach, which means it can test the entire baseband system without needing access to the actual hardware.
- The article explains how Hexagon Fuzz works and how it was able to discover several previously unknown vulnerabilities in Qualcomm's baseband processors, highlighting the importance of thorough security testing for critical components in mobile devices.
