Recurring patterns

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

Memory Corruption: Incorrect fixed argument count in ffi_prep_cif_var can corrupt memory on direct callbacks, especially on macOS aarch64. This is a high-severity native-level bug that can lead to crashes or arbitrary code execution.

Access Control: Using a shared temp directory without a username component allows local privilege escalation via directory permission conflicts. The fix isolates the directory per user.
