Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Privilege Escalation: Multiple historical fixes in execve address memory corruption, SUID jail bypass, and address space restoration failures, indicating a high-risk syscall with complex state management.

Certificate Validation Bypass: A series of fixes progressively added chain verification, hostname checks, key usage, and pathLenConstraint enforcement, showing TLS validation was historically incomplete and prone to bypass.

Use-After-Free: Fixes for stack-use-after-return and Executable lifetime issues indicate a fragile execution context management in the JS engine.
