DPA Countermeasures weakening on Series 3 devices_CVE-2026-4930

7.1 / 10

HIGH

CVSS:4.0/AV:P/AC:L/AT:N/PR:H/UI:N/VC:H/VI:N/VA:N/SC:H/SI:H/SA:H

Description

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
