The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Issue summary: OpenSSL CMP password based protection verification only checks whether the protectionAlg parameter was not NULL and not its ASN.1 type, before...

PT-2026-81300

Name of the Vulnerable Software and Affected Versions OpenSSL versions prior to 3.5.3-8.1 Description A double free issue exists in the QUIC server when processing an INITIAL packet. The default packet handler port default packet handler creates a QRX QUIC record layer RX object for packet...

PT-2026-81301

Name of the Vulnerable Software and Affected Versions OpenSSL versions 1.0.2 through 4.0 Description Receiving a DTLS record for a future epoch during a handshake causes the system to buffer significantly more memory than the record requires. This occurs because the software retains the entire re...

PT-2026-81304

Name of the Vulnerable Software and Affected Versions OpenSSL affected versions not specified Description An issue exists in the CMP response validation where the ossl cmp msg check update function converts a peer-supplied sender distinguished name using X509 NAME oneline and passes it directly a...

PT-2026-81305

Name of the Vulnerable Software and Affected Versions OpenSSL affected versions not specified Description The Certificate Management Protocol CMP caches additional certificates extraCerts sent in a CMP message but fails to remove them even if the message is rejected or the certificates are invali...

PT-2026-81306

Name of the Vulnerable Software and Affected Versions OpenSSL affected versions not specified Description When processing QUIC traffic, the QUIC stack may retain metadata for ACK-only packets for the entire duration of a connection if a peer repeatedly sends ack-eliciting packets without...

PT-2026-81307

Name of the Vulnerable Software and Affected Versions OpenSSL affected versions not specified Description An issue exists in the Certificate Management Protocol CMP password-based MAC protection verification. The library uses the X509 ALGOR get0 function to read the protectionAlg algorithm...

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...

CVE-2026-54874: Asymmetric Resource Consumption (Amplification)

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...

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-2026-63074: Allocation of Resources Without Limits or Throttling

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...

CVE-2026-63075: Allocation of Resources Without Limits or Throttling

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...
