CVE-2026-3579

wolfSSL 5.8.4 on RISC-V RV32I architectures lacks a constant-time software implementation for 64-bit multiplication. The compiler-inserted muldi3 subroutine executes in variable time based on operand values. This affects multiple SP math functions sp256mul9, sp256sqr9, etc., leading to a timing...

CVE-2026-3579 Non-constant time multiplication subroutine __muldi3 on RISC-V RV32I

wolfSSL 5.8.4 on RISC-V RV32I architectures lacks a constant-time software implementation for 64-bit multiplication. The compiler-inserted muldi3 subroutine executes in variable time based on operand values. This affects multiple SP math functions sp256mul9, sp256sqr9, etc., leading to a timing...

Linux Distros Unpatched Vulnerability : CVE-2026-3580

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - In wolfSSL 5.8.4, constant-time masking logic in sp256getentry2569 is optimized into conditional branches bnez by GCC when targeting RISC-V RV32I with -O3.

wolfSSL 安全漏洞

wolfSSL CyaSSL is a small, portable embedded SSL programming library developed by the US company wolfSSL, aimed at developers working with embedded systems. Version 5.8.4 of wolfSSL contains a security vulnerability. This vulnerability stems from the lack of a software implementation for 64-bit...

CVE-2026-3580: Observable Discrepancy

In wolfSSL 5.8.4, constant-time masking logic in sp256getentry2569 is optimized into conditional branches bnez by GCC when targeting RISC-V RV32I with -O3. This transformation breaks the side-channel resistance of ECC scalar multiplication, potentially allowing a local attacker to recover secret...
