      <description>&lt;p&gt;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.&lt;/p&gt;</description>

      <title>RUSTSEC-2026-0023 — X25519 secret validation did not check buffer length or clamping</title>
      <link>https://vulnerability.circl.lu/vuln/rustsec-2026-0023</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; crates.io: libcrux-ecdh&lt;/p&gt;
&lt;p&gt;The latest releases of the libcrux-ecdh crate contains the following
bug-fix:&lt;/p&gt;
&lt;p&gt;[#1301](https://github.com/cryspen/libcrux/pull/1301): Check length
and clamping in X25519 secret validation. This is a breaking change
since errors are now raised on unclamped X25519 secrets or inputs of
the wrong length&lt;/p&gt;</description>
