SM2-PKE has 32-bit Biased Nonce Vulnerability

Summary A critical vulnerability exists in the SM2 Public Key Encryption PKE implementation where the ephemeral nonce k is generated with severely reduced entropy. A unit mismatch error causes the nonce generation function to request only 32 bits of randomness instead of the expected 256 bits. Th...

Name of the Vulnerable Software and Affected Versions RustCrypto versions 0.14.0-pre.0 through 0.14.0-rc.0 Description The Elliptic Curves library within RustCrypto, a general-purpose Elliptic Curve Cryptography ECC implementation, contains a flaw in its SM2 Public Key Encryption PKE...

CVE-2025-53627 Meshtastic firmware allows forged DMs with no PKC to show up as encrypted

Meshtastic is an open source mesh networking solution. The Meshtastic firmware starting from version 2.5 introduces asymmetric encryption PKI for direct messages, but when the pkiencrypted flag is missing, the firmware silently falls back to legacy AES-256-CTR channel encryption. This was an...

PT-2025-51146

Name of the Vulnerable Software and Affected Versions Sequoia versions prior to 2.1.0 Description A flaw exists in Sequoia that, when provided with a short ciphertext during the aes key unwrap process, causes a panic. An attacker can exploit this to cause an application crash by sending a special...

CVE-2025-64767

hpke-js is a Hybrid Public Key Encryption HPKE module built on top of Web Cryptography API. Prior to version 1.7.5, the public SenderContext Seal API has a race condition which allows for the same AEAD nonce to be re-used for multiple Seal calls. This can lead to complete loss of Confidentiality...

librnp: Weak random number generation

Background librnp is a high performance C++ OpenPGP library. Description The affected librnp version generated weak session keys for its public key encryption PKESK mode. Impact Messages encrypted using the affected librnp version might be readable by an attacker with just the public key...
