DFG::ByteCodeParser::flush() Vulnerability
At (a), it should flush the scope register of inlineStackEntry->m_codeBlock instead of m_codeBlock. But it doesn't. As a result, the scope register of inlineStackEntry->m_codeBlock may have an incorrect offset in the stack layout phase. The proof-of-concept code provided throws an exception to trigger the vulnerability.
Mitigation:
Update to the latest version of the software.
