CVE-2026-87735: Improper Validation of Specified Quantity in Input

An issue was discovered in the mirage-crypto-pk package before 2.3.0 for OCaml. There is an undocumented exception for a small message during RSA decryption or encryption...

CVE-2026-87732: Improper Verification of Cryptographic Signature

An issue was discovered in the mirage-crypto package before 2.2.0 for OCaml. The AES.GCM.authenticatedecryptinto and Chacha20.authenticatedecryptinto functions write the decrypted plaintext into a caller-provided buffer and only then compares the tag. On a forged tag, the functions returns false,...

CVE-2026-87733: Improper Certificate Validation

An issue was discovered in the mirage-crypto-ec function before 2.2.0 for OCaml. The ECDSA functions P256,P384,P521.Dsa.pubofoctets accept 0x00, the encoding of the point at infinity, as a public key. With that public key, signatures can be forged without a private key...

CVE-2026-87737: Observable Timing Discrepancy

An issue was discovered in the mirage-crypto-ec package before 2.4.0 for OCaml. There is a timing side channel for NIST elliptic-curve scalar multiplication: the time required for a lookup can depend on a secret...

CVE-2026-87736: Out-of-bounds Read

An issue was discovered in the mirage-crypto-ec package before 2.3.0 for OCaml. There is an EC public key out-of-bounds read for compressed points...

crypto/x509: crypto/tls: golang: Go: Denial of Service vulnerability in certificate chain building

A flaw was found in the Go standard library packages crypto/x509 and crypto/tls. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being...

crypto/x509: golang: Go crypto/x509: Certificate validation bypass due to incorrect DNS constraint application

A flaw was found in the crypto/x509 package within Go golang. When verifying a certificate chain, excluded DNS Domain Name System constraints are not correctly applied to wildcard DNS Subject Alternative Names SANs if the case of the SAN differs from the constraint. This oversight could allow an...

crypto/x509: golang: Go crypto/x509: Denial of Service via inefficient certificate chain validation

A flaw was found in Go's crypto/x509 package. A remote attacker could exploit this by presenting a specially crafted certificate chain containing a large number of policy mappings. This inefficient validation process consumes excessive resources, which can lead to a denial of service DoS for...

crypto/tls: golang: Golang crypto/tls: Denial of Service via indefinite KeyUpdate messages

A flaw was found in the crypto/tls package, part of golang. A malicious client can exploit this vulnerability by continuously sending KeyUpdate messages to a server. This forces the server to perform indefinite key derivation operations, leading to resource exhaustion and a Denial of Service DoS...
