CVE-2026-4258
All versions of the package sjcl are vulnerable to Improper Verification of Cryptographic Signature due to missing point-on-curve validation in sjcl.ecc.basicKey.publicKey. An attacker can recover a victim's ECDH private key by sending crafted off-curve public keys and observing ECDH outputs. The...
CVE-2026-3230
A flaw was found in wolfSSL. A remote attacker could exploit a missing cryptographic step in the Transport Layer Security TLS 1.3 client HelloRetryRequest handshake logic. By sending a crafted HelloRetryRequest followed by a ServerHello message that omits the required keyshare extension, an...

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...

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-2026-4395
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...
CVE-2026-3230
wolfSSL’s TLS 1.3 client logic is affected by an improper key_share handling during HelloRetryRequest, allowing a crafted HelloRetryRequest followed by a ServerHello without the key_share extension to derive predictable traffic secrets from the (EC)DHE shared secret. Affected component: TLS hands...
CVE-2026-4395 Heap-based buffer overflow in wc_ecc_import_x963_ex KCAPI path
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...
CVE-2026-4395
CVE-2026-4395 affects wolfSSL wolfcrypt KCAPI ECC: a heap-based buffer overflow in wc_ecc_import_x963_ex() allows an attacker to write beyond the pubkey_raw buffer (132 bytes) when parsing a crafted oversized ECPoint in ServerKeyExchange. The path copies input to key->pubkey_raw via XMEMCPY wi...
