Root Cause Analysis
The vulnerability stems from two key issues: 1) In GlobOptFields.cpp
, the ProcessFieldKills
function was missing conditional checks for inlined functions with arguments, leading to improper field invalidation during array operations. 2) In Lower.cpp
, the NewScObjectNoCtor
handling lacked proper bailout checks and helper call logic, creating unsafe object initialization paths. Both were directly addressed in the security patches (936a5af/d797e3f) through added argument presence checks and bailout validation, correlating with the CWE-787 description of out-of-bounds writes via memory handling errors.
