      <title>CVE-2025-24802 — Soundness issue with Plonky2 look up tables</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2025-24802</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; 0xPolygonZero plonky2&lt;/p&gt;
&lt;p&gt;Plonky2 is a SNARK implementation based on techniques from PLONK and FRI. Lookup tables, whose length is not divisible by 26 = floor(num_routed_wires / 3) always include the 0 -&amp;gt; 0 input-output pair. Thus a malicious prover can always prove that f(0) = 0 for any lookup table f (unless its length happens to be divisible by 26). The cause of problem is that the LookupTableGate-s are padded with zeros. A workaround from the user side is to extend the table (by repeating some entries) so that its length becomes divisible by 26. This vulnerability is fixed in 1.0.1.&lt;/p&gt;</description>
