CVE-2021-1109

Data corruption and stream interruption via timing flaw

Published Aug 11, 2021 · Updated Aug 3, 2024

Timing flaws in NVIDIA Jetson camera firmware on Jetson Linux 32.x before 32.6.1 allow local users to corrupt data or interrupt streams. The firmware permits unauthorized modification of camera resources during a multistep operation whose timing can affect several concurrent streams. Exploitation requires high privileges and complex timing, and the published impact is limited to lost data integrity or denial of service rather than confidentiality.
