  "message": "Fix std::vector out-of-bounds access in Flutter Android JNI and Delegate (#187218)\n\nThis CL addresses potential `std::vector` index out-of-bounds errors in\nthe Flutter engine\u0027s Android native code, detected by libc++ hardening\n(go/cc-hardening-assertions). The issues stem from unsafe `\u0026vector[0]`\naccesses on potentially empty vectors.\n\n1. **platform_view_android_jni_impl.cc (SetViewportMetrics):** Added\nsize checks before using `GetIntArrayRegion` on vectors created from JNI\narrays, which can be empty.\n2. **platform_view_android_delegate.cc (UpdateSemantics):** Moved buffer\npointer initializations (e.g., `\u0026buffer[0]`) and their usage to be\nwithin `!empty()` checks, preventing access on zero-sized vectors.\n\nThese changes ensure safe vector handling, particularly when empty data\nis passed via JNI.\n\nSee cl/922343981",
