Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Memory Safety: Unsound FFI type signatures where mutable pointers are declared as immutable can lead to undefined compiler optimizations, undefined behavior, and potential memory corruption in Rust downstream consumers.
Side-Channel Attack: Non-constant-time comparison of secret buffers (such as checking if a session secret is zero) introduces timing side-channels that can leak information about cryptographic state.
