CVE-2021-34394

Service interruption via malformed OTE message deserialization

Published Jun 22, 2021 · Updated Aug 4, 2024

Buffer overflow in NVIDIA Trusty's OTE protocol on affected Jetson Linux releases allows local users to interrupt trusted applications. The message-stream deserializer accepts a malformed stream from a malicious client application and overruns a buffer while decoding it. Exploitation requires high local privileges and user interaction, and the resulting failure can interrupt Trusty trusted applications.
