UBUNTU-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...

Timing Attack

openssl is vulnerable to Timing Attack. An attacker with access to mount a local timing attack during the ECDSA signature generation is able to exploit the vulnerability in the ECC scalar mmultiplication to recover the private key...
