CVE ID :CVE-2026-4930

Published : June 25, 2026, 6:39 p.m. | 1 hour, 5 minutes ago

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

Severity: 7.1 | HIGH
