The commit 8264b9b addressing CVE-2018-8624 added overflow bailout checks when restoring induction variables. The vulnerability stemmed from missing overflow checks in loop memory operation handling, which could corrupt memory via JIT-compiled code. The affected code path in BackwardPass.cpp directly manipulated induction variables during memory operations without proper overflow safeguards prior to the patch, matching the CWE-787 (Out-of-bounds Write) description.
