CVE-2025-14972
MediumCVSS 4.1Exploitation Probability (EPSS)
Low risk3th percentile - higher than 3% of all known CVEs
Summary
Countermeasures for DPA within the SYMCRYPTO engine on SixG301xxx devices are not sufficiently random and will eventually repeat. KSU keys using SYMCRYPTO will be impacted by this vulnerability.
Risk Assessment
Repeating countermeasures may weaken cryptographic security, potentially enabling side-channel attacks (DPA) on KSU keys.
Recommendation
Apply updates provided by the manufacturer of SixG301xxx devices that improve the randomness of DPA countermeasures. Monitor manufacturer security advisories.
