Description

Trusty (the trusted OS produced by NVIDIA for Jetson devices) driver contains a vulnerability in the NVIDIA OTE protocol message parsing code where an integer overflow in a malloc() size calculation leads to a buffer overflow on the heap, which might result in information disclosure, escalation of privileges, and denial of service.

• CWE-190Integer Overflow or WraparoundThe product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
