CVE-2026-6839 Samsung Open Source CVE debrief

CVE-2026-6839 Improper validation of STRING tensor offsets in Samsung Open Source ONE could allow malformed string metadata to trigger out of bounds access during constant tensor import. Affected versions are prior to commit 1.30.0. This vulnerability impacts systems using Samsung Open Source ONE, particularly those with untrusted input or high-risk deployment contexts. Defenders should verify exposure, assess patching feasibility to version 1.30.0 or later, and monitor for potential out of bounds access attempts. The CVE record and NVD entry provide details, but there is limited information on exploitation scenarios. Confirm whether affected product deployments exist in managed

Who should care

Defenders responsible for systems using Samsung Open Source ONE, especially those with untrusted input or high-risk deployment contexts, should verify exposure and assess the feasibility of patching to version 1.30.0 or later.

Why it matters

CVE-2026-6839 Improper validation of STRING tensor offsets in Samsung Open Source ONE allows out of bounds access. Defenders should verify exposure, assess patching feasibility, and monitor for potential attacks.

  • Verify exposure in systems using Samsung Open Source ONE prior to version 1.30.0
  • Assess patching feasibility to version 1.30.0 or later
  • Monitor for potential out of bounds access attempts in affected systems

Technical summary

The vulnerability is due to improper validation of STRING tensor offsets in Samsung Open Source ONE, which could allow malformed string metadata to trigger out of bounds access during constant tensor import. The affected version is prior to commit 1.30.0.

Defensive priority

Defenders should prioritize verifying exposure in systems using Samsung Open Source ONE, especially those with untrusted input or high-risk deployment contexts, and assess if patching to version 1.30.0 or later is feasible.

Recommended defensive actions

  • Verify if systems using Samsung Open Source ONE are exposed by checking versions prior to 1.30.0
  • Assess the feasibility of patching to version 1.30.0 or later
  • Monitor for potential out of bounds access attempts in systems using affected versions

Evidence notes

The CVE record and NVD entry provide details on the vulnerability, including its description, affected versions, and CVSS score. However, there is limited information on potential exploitation or specific attack scenarios.
