TL;DR

On RISC-V RV32I, 64-bit multiplication relies on a non-constant-time helper that varies with operand values, leaking timing information through multiple SP math routines. Local timing analysis could recover sensitive intermediate values. The fix replaces the behavior with a constant-time implementation.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range.

Background info

wolfSSL.wolfssl is vulnerable to Observable Timing Discrepancy in versions 0.0.1 - 5.8.4.

How to fix this

Upgrade the wolfSSL.wolfssl library to the patch version.
