Exploitability

CWE

KEV

CWE ID	Description
CWE-190	The 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.

Attack-Flow Graph

Executive Summary

This vulnerability is an integer overflow in the buffer size calculation within Samsung Open Source ONE. It occurs when handling large tensors, which can cause the program to miscalculate the buffer size and potentially access memory outside the intended bounds.

Impact Analysis

The integer overflow can lead to out of bounds memory access, which may result in memory corruption or crashes. According to the CVSS score, it has a low complexity and requires user interaction, with impacts including low confidentiality and integrity loss, and high availability impact.

Mitigation Strategies

To mitigate this vulnerability, update Samsung Open Source ONE to version 1.30.0 or later, as the affected versions are prior to commit 1.30.0.
