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