CVE-2026-4930 (GCVE-0-2026-4930)
Vulnerability from cvelistv5 – Published: 2026-06-25 18:39 – Updated: 2026-06-25 19:03
VLAI
Title
DPA Countermeasures weakening on Series 3 devices
Summary
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
