CVE-2026-24783
No affected components available
soroban-fixed-point-math is a fixed-point math library for Soroban smart contacts. In versions 1.3.0 and 1.4.0, the mulDiv(x, y, z) function incorrectly handled cases where both the intermediate product $x * y$ and the divisor $z$ were negative. The logic assumed that if the intermediate product was negative, the final result must also be negative, neglecting the sign of $z$. This resulted in rounding being applied in the wrong direction for cases where both $x * y$ and $z$ were negative. The functions most at risk are fixed_div_floor and fixed_div_ceil, as they often use non-constant numbers as the divisor $z$ in mulDiv. This error is present in all signed FixedPoint and SorobanFixedPoint implementations, including i64, i128, and I256. Versions 1.3.1 and 1.4.1 contain a patch. No known workarounds for this issue are available.
