CVE-2026-51808

Buffer Overflow vulnerability in OpenHTJ2K v.0.18.4 and before allows an attacker to execute arbitrary code via the openhtj2kdecoderimpl::invoke, invokelinebased, invokelinebasedstream, and invokelinebasedpredecoded function in source/core/interface/decoder.cpp...

CVE-2026-51807

Heap-based out-of-bounds write in j2kprecinctsubband::parsepacketheader in OpenHTJ2K versions 0.18.3 and earlier fixed in v0.18.4 caused by missing bounds validation before coding-pass lengths are written to j2kcodeblock::passlength128. A crafted JPEG 2000 codestream containing malformed PPM pack...

Security Bulletin: IBM i is Affected By Multiple Vulnerabilities in OpenSSL

Summary OpenSSL for IBM i is vulnerable to out-of-bounds read when parsing a crafted DER-encoded ASN.1 structure with a 2 gigabyte primitive element or when using Cryptographic Message Services CMS password-based decryption and processing a stream-mode KEK cipher CVE-2026-34180, CVE-2026-9076,...

kernel: crypto: ccp - copy IV using skcipher ivsize

A flaw was found in the Linux kernel's cryptographic coprocessor CCP driver. When processing AFALG rfc3686-ctr-aes-ccp requests, the ccpaescomplete function attempts to restore more data than the allocated buffer for the Initialization Vector IV can hold. This leads to a buffer overrun, which can...

JLSEC-2026-734 Out-of-bounds write in the Renesas TSIP TLS 1.3 transcript buffer

Out-of-bounds write in the Renesas TSIP TLS 1.3 transcript buffer. In tsipStoreMessage the capacity check guarding the fixed message bag MSGBAGSIZE sets an error code but fails to return, so execution falls through to an XMEMCPY that writes past the end of the buffer once the accumulated TLS 1.3...

In wolfSSL before 5.5.2, if callback functions are enabled via the WOLFSSLCALLBACKS flag, then a malicious TLS 1.3 client or network attacker can trigger a buffer over-read on the heap of 5 bytes. WOLFSSLCALLBACKS is only intended for debugging...

JLSEC-2026-678 In wolfSSL prior to 5.6.6, if callback functions are enabled (via the `WOLFSSL_CALLBACKS` flag),...

JLSEC-2026-754 The PKCS#7 decode path ignores the caller-supplied output buffer size (outputSz), allowing decoded...

The PKCS7 decode path ignores the caller-supplied output buffer size outputSz, allowing decoded content to be written past the bounds of the provided buffer. This affects wolfSSL 5.9.0 and earlier and was fixed in the 5.9.1 release...

JLSEC-2026-708

Heap Overflow in TLS 1.3 ECH parsing. An integer underflow existed in ECH extension parsing logic when calculating a buffer length, which resulted in writing beyond the bounds of an allocated buffer. Note that in wolfSSL, ECH is off by default, and the ECH standard is still evolving...

JLSEC-2026-707 Two buffer overflow vulnerabilities existed in the wolfSSL CRL parser when parsing CRL numbers: a...

Two buffer overflow vulnerabilities existed in the wolfSSL CRL parser when parsing CRL numbers: a heap-based buffer overflow could occur when improperly storing the CRL number as a hexadecimal string, and a stack-based overflow for sufficiently sized CRL numbers. With appropriately crafted CRLs,...

JLSEC-2026-753 A heap buffer overflow could occur in the DTLS 1.3 ACK serialization path before the connecting peer...

A heap buffer overflow could occur in the DTLS 1.3 ACK serialization path before the connecting peer is authenticated. The buffer overflow was due to an integer truncation when computing the length of the ACK record-number list, causing an undersized buffer to be allocated and then overrun. This...

JLSEC-2026-719

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...

JLSEC-2026-691 A stack buffer overflow vulnerability exists in wolfSSL's PKCS7 SignedData encoding functionality

A stack buffer overflow vulnerability exists in wolfSSL's PKCS7 SignedData encoding functionality. In wcPKCS7BuildSignedAttributes, when adding custom signed attributes, the code passes an incorrect capacity value esd-signedAttribsCount to EncodeAttributes instead of the remaining available space...

A 1-byte stack buffer over-read was identified in the MatchDomainName function src/internal.c during wildcard hostname validation when the LEFTMOSTWILDCARDONLY flag is active. If a wildcard exhausts the entire hostname string, the function reads one byte past the buffer without a bounds check,...

JLSEC-2026-724 X.509 date buffer overflow in `wolfSSL_X509_notAfter` / `wolfSSL_X509_notBefore`

X.509 date buffer overflow in wolfSSLX509notAfter / wolfSSLX509notBefore. A buffer overflow may occur when parsing date fields from a crafted X.509 certificate via the compatibility layer API. This is only triggered when calling these two APIs directly from an application, and does not affect TLS...
