CVE-2021-1070

Service interruption via writable device tree files

Published Jan 26, 2021 · Updated Aug 3, 2024

Improper access control in NVIDIA Jetson L4T before 32.5 allows local users to modify system device tree files and interrupt service. NVIDIA identifies apply_binaries.sh as the locus but has not published which access-control operation or file permissions are incorrect. Low-privilege local access is required; altering the device tree can render the Jetson system unavailable.
