JLSEC-2026-683 An issue was discovered in wolfSSL before 5.7.0

An issue was discovered in wolfSSL before 5.7.0. A safe-error attack via Rowhammer, namely FAULT+PROBE, leads to ECDSA key disclosure. When WOLFSSLCHECKSIGFAULTS is used in signing operations with private ECC keys, such as in server-side TLS connections, the connection is halted if any fault...

JLSEC-2026-726 wolfSSL's ECCSI signature verifier `wc_VerifyEccsiHash` decodes the `r` and `s` scalars from the...

wolfSSL's ECCSI signature verifier wcVerifyEccsiHash decodes the r and s scalars from the signature blob via mpreadunsignedbin with no check that they lie in 1, q-1. A crafted forged signature could verify against any message for any identity, using only publicly-known constants...

JLSEC-2026-713

Heap-based buffer overflow in the KCAPI ECC code path of wceccimportx963ex in wolfSSL wolfcrypt allows a remote attacker to write attacker-controlled data past the bounds of the pubkeyraw buffer via a crafted oversized EC public key point. The WOLFSSLKCAPIECC code path copies the input to...

Missing hash/digest size and OID checks allow digests smaller than allowed when verifying ECDSA certificates, or smaller than is appropriate for the relevant key type, to be accepted by signature verification functions. This could lead to reduced security of ECDSA certificate-based authentication...

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...

PYSEC-2026-1325 Minerva timing attack on P-256 in python-ecdsa

python-ecdsa has been found to be subject to a Minerva timing attack on the P-256 curve. Using the ecdsa.SigningKey.signdigest API function and timing signatures an attacker can leak the internal nonce which may allow for private key discovery. Both ECDSA signatures, key generation, and ECDH...

CVE-2026-12340

Out-of-bounds heap read during SM2/SM3 certificate signature verification. When parsing a certificate with an SM3wSM2 signature, the Subject Key Identifier computation reads the trailing 65 bytes of the public key without checking that the key is at least that long. A public key shorter than 65...

The X25519 x8664 assembly implementation fails to clear the most significant bit during the final modular reduction, so the computed result may not be fully reduced modulo the field prime 2^255 - 19. This can leave the field element in a non-canonical form, producing an incorrect result from the...
