CVE-2026-63072: Out-of-bounds Write

Issue summary: OpenSSL CMS decryption sizes the key-unwrap output buffer based on querying the unwrapped key size, but the AES-WRAP-PAD unwrap primitive can write and cleanse more bytes than that query reports, causing an 8-byte out-of-bounds heap write. Impact summary: An attacker who supplies a...

CVE-2026-63076: NULL Pointer Dereference

Issue summary: OpenSSL CMP password based protection verification only checks whether the protectionAlg parameter was not NULL and not its ASN.1 type, before treating it as a PBMParameter. A crafted message can contain a parameter of a different type, which is then dereferenced as an invalid...

CVE-2026-14457: NULL Pointer Dereference

Issue summary: In a server or client configuration with RFC7250 Raw Public Keys RPKs enabled, and only the private key with no associated certificate configured locally, a NULL pointer dereference may occur when the remote peer solicits raw public keys and also sends the typically omitted...

Excessive Memory Use Buffering DTLS Records for a Future Epoch

Issue summary: Receiving a DTLS record for a future epoch while a handshake is in progress causes OpenSSL to buffer far more memory than the record itself requires. Impact summary: A peer can use a small amount of network traffic to make an OpenSSL DTLS endpoint retain a disproportionately large...

Heap Buffer Overflow in CMS Key Unwrapping

Issue summary: OpenSSL CMS decryption sizes the key-unwrap output buffer based on querying the unwrapped key size, but the AES-WRAP-PAD unwrap primitive can write and cleanse more bytes than that query reports, causing an 8-byte out-of-bounds heap write. Impact summary: An attacker who supplies a...

Untrusted Sender DN Used as Format String in CMP Response Validation

Issue summary: OpenSSL CMP response validation passed an unexpected response sender distinguished name directly as the format string to ERRraisedata. Impact summary: A malicious or intercepted CMP endpoint can crash a CMP client that enforces an expected sender or uses a pinned server certificate...

QUIC ACK-only Packet Retention Can Cause Memory Exhaustion

Issue summary: When OpenSSL processes QUIC traffic from a peer that repeatedly sends ack-eliciting packets while not acknowledging ACK-only responses, the QUIC stack can retain ACK-only packet metadata for the lifetime of the connection. Impact summary: A remote peer that can complete a QUIC...

CMP Indefinite Cache Growth of ExtraCerts

Issue summary: The OpenSSL Certificate Management Protocol CMP caches additional certificates extraCerts sent in a CMP message, but never expunges them for instance if they are invalid. If a server reuses an OSSLCMPCTX frequently, this cache of extraCerts may grow unboundedly, and a malicious...

RPK Server Signature Algorithm Selection Can Dereference a Missing Certificate

Issue summary: In a server or client configuration with RFC7250 Raw Public Keys RPKs enabled, and only the private key with no associated certificate configured locally, a NULL pointer dereference may occur when the remote peer solicits raw public keys and also sends the typically omitted...

Invalid Pointer Dereference in CMP Server via Crafted protectionAlg

Issue summary: OpenSSL CMP password based protection verification only checks whether the protectionAlg parameter was not NULL and not its ASN.1 type, before treating it as a PBMParameter. A crafted message can contain a parameter of a different type, which is then dereferenced as an invalid...

OpenSSL -- Multiple vulnerabilities

The OpenSSL poject reports: Heap Buffer Overflow in CMS Key Unwrapping CVE-2026-63072 Moderate Invalid Pointer Dereference in CMP Server via Crafted protectionAlg CVE-2026-63076 Moderate RPK Server Signature Algorithm Selection Can Dereference a Missing Certificate CVE-2026-14457 Low Excessive...

AEAD Forgeries with Empty Ciphertext When Using EVP_Cipher()

Issue summary: ChaCha20-Poly1305 and AES-OCB decryption with an empty ciphertext can report success without verifying the supplied authentication tag when the operation is finalized by calling the EVPCipher function. Impact summary: Applications calling EVPCipher on an empty ciphertext and...

QUIC Server May Trigger Double Free When Processing INITIAL Packet

Issue summary: QUIC server may double free QRX QUIC record layer RX object when channel creation fails for initial packet. Impact summary: Double free leads to heap corruption, which typically results in termination of QUIC server process, leading to Denial of Service. There is so far no evidence...
