CVE-2025-62496

The CVE refers to QuickJS: BigInt parsing in js_bigint_from_string. When converting a decimal string with an extremely large number of digits, the code computes n_bits as (n_digits × 27 + 7) / 8. For very large inputs (e.g., tens of millions of digits), this intermediate value overflows a 32-bit ...
