Root Cause Analysis
The commit diffs directly modify these functions to address memory safety issues. For IRBuilder::GetEnvironmentOperand
, the patch introduces environment reload logic to prevent stale pointer usage (critical for preventing OOB writes). For Inline::MapFormals
, the added JIT optimization flag ensures proper register tracking, mitigating corruption risks. Both changes align with the CWE-787 (out-of-bounds write) description and the RCE vulnerability pattern in JIT engine memory handling.
