Miggo AIRoot Cause AnalysisThe vulnerability stems from missing handling of Array Concat operations in ChakraCore's JIT optimizer. The commit adds IR::HelperArray_Concat to two critical locations: 1) In CheckJsArrayKills, where array segment metadata is updated, and 2) In ProcessArrayValueKills, where live array tracking is cleared. Without these checks, the optimizer would fail to invalidate array buffer assumptions after concat operations, leading to type confusion and out-of-bounds writes when optimized code accesses arrays based on incorrect memory layout assumptions.
