Root Cause Analysis
The vulnerability stemmed from improper handling of argument emission sequences when array destructuring introduced try/catch/finally blocks. The patch replaced direct ArgOut
emission with temporary storage (via EmitArgsWithArgOutsAtEnd
) and modified EmitArgs
/EmitSpreadArgToListBytecodeInstr
. The original functions lacked safeguards for intermediate exception handling, making them susceptible to memory corruption during bailout scenarios.
