Out-of-Bounds Write in Samsung Mobile Devices (CVE‑2025‑21043) Enables Remote Code Execution

What It Is – Samsung’s libimagecodec.quram.so library on its mobile devices contains an out‑of‑bounds write flaw that can be triggered remotely to execute arbitrary code.

Exploitability – The vulnerability is exploitable over the network; a proof‑of‑concept exists, but no public ransomware or malware campaign has been observed yet. CVSS (NVD) rates it 9.8 High.

Affected Products – All Samsung smartphones and tablets that ship with the vulnerable libimagecodec.quram.so library (e.g., Galaxy S22‑S23 series, Galaxy Tab S8, etc.).

Why It Matters for Trust & Control Assurance

  • Secure Configuration Management – Demonstrating that every endpoint runs an approved, patched firmware version is a core control objective across SOC 2, ISO 27001, NIST CSF and others.
  • Vulnerability Management Evidence – Timely patching and documented remediation provide defensible audit evidence of a mature risk‑mitigation process.
  • Continuous Monitoring – Automated MDM telemetry that records patch status feeds directly into a Trust Center, enabling real‑time assurance for auditors and enterprise buyers.

Recommended Actions

  1. Deploy Samsung’s latest security patch or firmware update immediately.
  2. Enforce MDM policies that block devices with out‑dated libimagecodec versions.
  3. Log patch‑deployment dates and device‑compliance status in your evidence repository for audit readiness.
