An electromagnetic-wave side-channel issue was discovered on NXP SmartMX / P5x security microcontrollers and A7x secure authentication microcontrollers, with CryptoLib through v2.9. It allows attackers to extract the ECDSA private key after extensive physical access (and consequently produce a clone). This was demonstrated on the Google Titan Security Key, based on an NXP A7005a chip. Other FIDO U2F security keys are also impacted (Yubico YubiKey Neo and Feitian K9, K13, K21, and K40) as well as several NXP JavaCard smartcards (J3A081, J2A081, J3A041, J3D145_M59, J2D145_M59, J3D120_M60, J3D082_M60, J2D120_M60, J2D082_M60, J3D081_M59, J2D081_M59, J3D081_M61, J2D081_M61, J3D081_M59_DF, J3D081_M61_DF, J3E081_M64, J3E081_M66, J2E081_M64, J3E041_M66, J3E016_M66, J3E016_M64, J3E041_M64, J3E145_M64, J3E120_M65, J3E082_M65, J2E145_M64, J2E120_M65, J2E082_M65, J3E081_M64_DF, J3E081_M66_DF, J3E041_M66_DF, J3E016_M66_DF, J3E041_M64_DF, and J3E016_M64_DF).
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 4.2, but requires specific conditions to be met without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), for affected systems. Impacting 45 products from ftsafe, from ftsafe, from ftsafe and 42 others, organizations running these solutions should prioritize assessment and patching.
Reported in 2021, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For ftsafe's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
