GHSA-9M44-RR2W-PPP7 Swift Crypto: X-Wing HPKE Decapsulation Accepts Malformed Ciphertext Length

Summary The X-Wing decapsulation path accepts attacker-controlled encapsulated ciphertext bytes without enforcing the required fixed ciphertext length. The decapsulation call is forwarded into a C API, which expects a compile-time fixed-size ciphertext buffer of 1120 bytes. This creates an FFI...

RUSTSEC-2026-0025 Panic in `libcrux-psq` on decryption of malformed AES-GCM ciphertext

The latest releases of the libcrux-psq crate contains the following bug-fix: 1319: Propagate AEADError instead of panicking The issue fixed in 1319 was first reported by Nadim Kobeissi...

GHSA-753P-WRJ5-G8FJ PQClean has a correctness error in HQC decapsulation

Impact A correctness error has been identified in the reference implementation of the HQC key encapsulation mechanism. Due to an indexing error, part of the secret key is incorrectly treated as non-secret data. This results in an incorrect shared secret value being returned when the decapsulation...
