CVE-2026-32280 Unexpected work during chain building in crypto/x509

During chain building, the amount of work that is done is not correctly limited when a large number of intermediate certificates are passed in VerifyOptions.Intermediates, which can lead to a denial of service. This affects both direct users of crypto/x509 and users of crypto/tls...

CVE-2026-32283 Unauthenticated TLS 1.3 KeyUpdate record can cause persistent connection retention and DoS in crypto/tls

If one side of the TLS connection sends multiple key update messages post-handshake in a single record, the connection can deadlock, causing uncontrolled consumption of resources. This can lead to a denial of service. This only affects TLS 1.3...

CVE-2026-32877

A flaw was found in Botan, a C++ cryptography library. During SM2 decryption, the library failed to validate the length of the authentication code value C3 before comparison. A remote attacker could exploit this by providing a specially crafted invalid ciphertext, leading to a heap over-read of u...

CVE-2026-34871

A predictable seed in a Pseudo-Random Number Generator (PRNG) affects Mbed TLS (before 3.6.6 and 4.x before 4.1.0) and TF-PSA-Crypto (before 1.1.0). Specifically, on systems where getrandom() is unavailable, /dev/urandom is used as a fallback instead of /dev/random . The impact of this vulnerabil...
