CVE-2022-42269

Data disclosure and alteration via unvalidated SMC input

Published Dec 30, 2022 · Updated Apr 10, 2025

Improper input validation in NVIDIA Trusted OS on Jetson Linux before 32.7.2 allows local users to disclose or alter data. The SMC call handler accepts untrusted input without the required validation; NVIDIA has not disclosed the affected parameter or downstream operation. Exploitation requires highly privileged local access, and the resulting disclosure or integrity compromise can cross component boundaries.
