Technical ContextAI · show details
This vulnerability is classified as Deserialization of Untrusted Data (CWE-502), which allows attackers to execute arbitrary code through malicious serialized objects. Trusty contains a vulnerability in the NVIDIA OTE protocol that is present in all TAs. An incorrect message stream deserialization allows an attacker to use the malicious CA that is run by the user to cause the buffer overflow, which may lead to information disclosure and data modification. Affected products include: Nvidia Jetson Linux.

SSVC AssessmentENISA
Priority Score
Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
Insecure deserialization occurs when an application converts serialized data (a stream of bytes representing an object's state) back into a living object without proper validation.
Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
