Miggo AIRoot Cause Analysis

While no patch diffs are available, analysis focuses on: 1) CWE-787 pattern matches ChakraCore's JIT optimization and typed array handling 2) Historical precedent for similar CVEs in these components 3) Microsoft's description of memory handling improvements. The identified functions represent core memory write operations and JIT optimization points where missing bounds checks could enable OOB writes. Confidence is medium due to indirect evidence from vulnerability characteristics and component architecture.
