Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Use After Free: Concurrency issues during JNI garbage collection can cause multiple threads to finalize YogaNodes simultaneously, leading to undefined behavior and use-after-free states during tree mutation. Developers must use safe allocation/deallocation patterns that isolate tree mutations from concurrent finalizer threads.
Memory Corruption: Accessing children of a layout node by index without verifying bounds leads to out-of-bounds array reads and potential memory corruption. All layout wrappers must explicitly validate index boundaries before calling underlying retrieval functions.
