# CVE-2026-4930

> 7.1 HIGH

## Beschreibung

SYMCRYPTO is the SiXG301's host side hardware engine accessed by PSA crypto library that accelerates symmetric cryptographic operations (AES encryption/decryption and hashing).


DPA Countermeasures on SYMCRYPTO can be weakened (reduced entropy) by forcing certain seed values if an attacker gains code execution capability on the impacted device.

  *  Therefore, the keys loaded on SYMCRYPTO may be more vulnerable to extraction through DPA attacks than intended
