CVE-2026-3503

Protection mechanism failure in wolfCrypt post-quantum implementations (ML-KEM and ML-DSA) in wolfSSL on ARM Cortex-M microcontrollers allows a physical attacker to compromise key material and/or cryptographic outcomes via induced transient faults that corrupt or redirect seed/pointer values during Keccak-based expansion. This issue affects wolfSSL (wolfCrypt): commit hash d86575c766e6e67ef93545fa69c04d6eb49400c6.

Summary		(es) Falla del mecanismo de protección en las implementaciones post-cuánticas de wolfCrypt (ML-KEM y ML-DSA) en wolfSSL en microcontroladores ARM Cortex-M permite a un atacante físico comprometer material de clave y/o resultados criptográficos a través de fallas transitorias inducidas que corrompen o redirigen valores de semilla/puntero durante la expansión basada en Keccak. Este problema afecta a wolfSSL (wolfCrypt): hash de commit d86575c766e6e67ef93545fa69c04d6eb49400c6.
