CVE-2021-1108

Local system disruption and disclosure via integer underflow

Published Aug 11, 2021 · Updated Aug 3, 2024

FuSa Capture integer underflow in NVIDIA Jetson Linux before 32.6.1 and SHIELD Experience before 9.0 allows local users to interrupt operation. FuSa Capture (VI/ISP) fails to validate an input before subtraction, allowing the resulting integer value to underflow. Low-privileged local access is required; exploitation can disclose information or alter data across system processes.
