This flaw leads to an incorrect length being used when a tensor exceeds a certain size, allowing memory corruption through an oversized tensor. The vulnerability is classified as CWE-190, indicating a numeric safety flaw that can compromise data integrity.", "risk_and_exploitability": "The CVSS score of 6.6 places the bug in the Medium severity range, and the lack of an EPSS score or KEV listing suggests it is not widely exploited at this time. The vulnerability can only be triggered when a tensor of sufficient size is processed, implying that an attacker would require the ability to influence tensor inputs to the library. The resulting memory corruption could potentially lead to code execution or system instability, but an active exploitation path has not been documented."}}}}, "created": "2026-04-22T07:30:11.593104+00:00", "title": "Integer Overflow Causing Memory Corruption in Samsung ONE Tensor Copy", "updated": "2026-04-22T07:30:11.593114+00:00", "vendors": []}
