JANUS: Agentic Cross-Language Fuzzing Harness Generation for Android Native Libraries
An agentic fuzzer automatically generates cross-language harnesses for Android JNI libraries, bridging the gap where memory-safe runtimes meet unsafe native code—relevant for mobile-heavy enterprise fleets.
Summary written by editorial AI · Source link below
arXiv:2610.30218v1 Announce Type: cross Abstract: Modern Android apps extensively rely on native libraries, bridging Java/Kotlin and C/C++ through the Java Native Interface (JNI). This cross-language interoperation, however, exposes the memory-safe Android Runtime to the unsafe C/C++ world, creating an attack surface that has been repeatedly exploited for full device compromise. While fuzzing is a proven technique for vetting native libraries, state-of-the-art harness generation tools struggle
Editorial Analysis
Enterprises with large Android app portfolios often undertest JNI boundaries; automated cross-language fuzzing could surface memory-corruption bugs before attackers do.
Include JNI boundary testing in your mobile app security programme, leveraging agentic fuzzing where manual harness creation is impractical.
