CVE-2023-25520

Denial of service via invalid boot settings

Published Jun 23, 2023 · Updated Nov 7, 2024

Improper input validation in NVIDIA Jetson Linux before 32.7.4 allows privileged local users to cause denial of service through nvbootctrl. The utility accepts and applies invalid boot-control settings instead of rejecting them; NVIDIA has not disclosed the specific fields or validation failure. Administrative privileges and local access are required, and exploitation interrupts the affected Jetson device without reported confidentiality or integrity impact.
