You can audit unsafe Rust by scanning unsafe blocks and fns to verify pointer alignment, check memory initialization, and enforce explicit SAFETY comments. This surfaces safety invariant violations and risky aliasing patterns, providing structured remediation suggestions to prevent undefined behavior.

Common unsafe Rust FFI pitfalls include incorrect data layout, unsafe aliasing across boundaries, and thread-safety issues in exported interfaces. Scanning for these FFI pitfalls verifies correct data layout and flags risky patterns in FFI bindings for remediation.

Yes, explicit SAFETY comments are required for unsafe Rust blocks and functions. Auditing unsafe code detects missing safety documentation and requires explicit SAFETY comments to verify non-null pointers, aligned pointers, and lifetime invariants before clearing the code.

To verify pointer alignment and lifetimes in unsafe Rust, you analyze unsafe blocks to check non-null and aligned pointers, validate memory initialization, and enforce lifetime invariants. This identifies unsafe aliasing and provides safe wrappers where possible.

Yes, it checks memory initialization invariants in Rust low-level abstractions. By analyzing unsafe code across libraries and binaries, it verifies initialization invariants and flags risky patterns that could lead to undefined behavior.

The best way to prevent undefined behavior in Rust FFI bindings is to enforce safety invariants, verify non-null and aligned pointers, and scan for common FFI pitfalls. This ensures correct data layout and thread-safety in exported interfaces.
