CVE-2026-76234
HighCVSS 7.5Summary
libcrux-ecdh and libcrux-ed25519 before 0.0.6, and libcrux-psq before 0.0.7, contain cryptographic implementation bugs. libcrux-ecdh did not properly check length and clamping during X25519 secret validation (and had a broken clamping check for imported X25519 secret keys); libcrux-ed25519 performed a duplicated clamping step during key generation; and libcrux-psq panicked instead of propagating an AEADError. These were fixed in the respective patched releases.
Risk Assessment
Cryptographic implementation bugs can lead to weakened key security, incorrect signature behavior, or service crashes, potentially compromising data confidentiality and integrity.
Recommendation
Upgrade libcrux-ecdh and libcrux-ed25519 to version 0.0.6 or later, and libcrux-psq to version 0.0.7 or later to obtain the fixes.
