CVE-2026-3580

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...

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-2026-3580

In wolfSSL 5.8.4, GCC optimizes constant-time masking logic in sp_256_get_entry_256_9 into conditional branches (bnez) when targeting RISC-V RV32I with -O3, breaking the expected side-channel resistance of ECC scalar multiplication. This may enable a local attacker to recover secret keys via timi...
