CVE-2025-24802: Plonky2 Zero Padding Lookup Tablecve-2025-24802-plonky2-zero-padding-lookup-table
Zero-padding lookup table slots implicitly introduces a (0, 0) entry. This undermines the soundness of the zero-knowledge proof by allowing a malicious prover to prove f(0) = 0 for any lookup table. To fix, pad unused slots with a valid lookup table entry (e.g., the first element).
