Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Integer Overflow: Incorrect casting of signed integers to unsigned before executing right-shift operations led to faulty carry/borrow calculations (e.g., in subborrowx operations for Curve25519 and P-224). This can compromise the constant-time properties or mathematical correctness of the cryptographic primitives, potentially enabling side-channel attacks or private key leakage.
