CVE-2026-5187

Two potential heap out-of-bounds write locations existed in DecodeObjectId in wolfcrypt/src/asn.c. First, a bounds check only validates one available slot before writing two OID arc values out0 and out1, enabling a 2-byte out-of-bounds write when outSz equals 1. Second, multiple callers pass...

CVE-2026-5295

A stack buffer overflow exists in wolfSSL's PKCS7 implementation in the wcPKCS7DecryptOri function in wolfcrypt/src/pkcs7.c. When processing a CMS EnvelopedData message containing an OtherRecipientInfo ORI recipient, the function copies an ASN.1-parsed OID into a fixed 32-byte stack buffer...

Stack-based Buffer Overflow

Overview Affected versions of this package are vulnerable to Stack-based Buffer Overflow in the wcPKCS7DecryptOri function when processing a CMS EnvelopedData message containing an OtherRecipientInfo recipient. An attacker can execute arbitrary code or cause a crash by sending a crafted message...

CVE-2026-5194

A flaw was found in wolfSSL. Missing hash/digest size and Object Identifier OID checks allow the acceptance of smaller, less secure digests during the verification of Elliptic Curve Digital Signature Algorithm ECDSA certificates. This could enable a remote attacker, with knowledge of the public...

EUVD-2026-21070

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...
