CVE-2026-74900

openssl_encrypt before version 1.4.0 has a flaw in pqc.py: when KEM decapsulation fails, it silently falls back to simulation mode, deriving a deterministic shared secret from just 16 bytes of the private key plus public encapsulated key data. An attacker with those 16 private-key bytes can compu...

The X25519 x8664 assembly implementation fails to clear the most significant bit during the final modular reduction, so the computed result may not be fully reduced modulo the field prime 2^255 - 19. This can leave the field element in a non-canonical form, producing an incorrect result from the...
