Frequently Asked Questions
What is CVE-2026-4930?
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
Is CVE-2026-4930 actively exploited?
No confirmed active exploitation of CVE-2026-4930 has been reported, but organizations should still patch proactively.
How to fix CVE-2026-4930?
No patch is currently available. Monitor vendor advisories for updates.
What is the CVSS score for CVE-2026-4930?
No CVSS score has been assigned yet.

Weaknesses (CWE)
CWE-331 — Insufficient Entropy: The product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others.
- [Implementation] Determine the necessary entropy to adequately provide for randomness and predictability. This can be achieved by increasing the number of bits of objects such as keys and seeds.
