CVE-2021-1071

System power data disclosure via INA3221 access controls

Published Jan 26, 2021 · Updated Aug 3, 2024

Improper access control in NVIDIA Jetson L4T before r32.5 allows local users to read system power usage data through the INA3221 driver. The INA3221 driver exposes power-usage readings without adequately restricting access, but NVIDIA has not identified the affected interface or permission check. A local low-privileged account and high attack complexity are required; the reported consequence is disclosure only.
