CVE-2026-76234 Details

UNDERGOING ENRICHMENT

The CVE is currently being enriched by the Volerion team. The enrichment process results in the association of reference link tags, CVSS, and CPE applicability statement data.

Description

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.
