SixG301xxx CVE-2025-14972

Apply firmware updates from Silicon Labs addressing CVE-2025-14972 when released. Monitor the Silicon Labs security advisory at https://community.silabs.com/068Vm00000M3cAX for patch availability and specific firmware version numbers. If patches are not immediately available or deployment is infeasible, implement physical security controls as compensating measures: restrict physical access to devices through tamper-evident enclosures, deploy devices in monitored or restricted-access locations, implement tamper detection circuitry that erases keys upon physical intrusion attempts, and establish procedures for secure device decommissioning that ensure cryptographic key erasure. For new deployments, consider alternative Silicon Labs device families with validated side-channel resistance if physical security cannot be guaranteed. Organizations with high-security requirements should perform risk assessment of previously deployed devices to determine if key rotation or device replacement is warranted, particularly for devices that may have been in adversary-accessible locations. Note that physical security measures add operational complexity and cost but are the only effective mitigation prior to firmware patches.
