Out-of-Bounds Write in Samsung Mobile Devices (CVE‑2025‑21042) Enables Remote Code Execution
What It Is – Samsung’s Android‑based smartphones and tablets contain an out‑of‑bounds write flaw in the native library libimagecodec.quram.so. The defect can be triggered by crafted image data, allowing an attacker to write beyond the intended memory region.
Exploitability – The vulnerability is remotely exploitable without authentication. Public proof‑of‑concept code has been released, and the CVSS v3.1 base score is 8.8 (High).
Affected Products – All Samsung mobile devices shipping the vulnerable library version (typically devices running Android 12‑13 with the affected firmware).
Why It Matters for Trust & Control Assurance
- Vulnerability Management – Demonstrates the need for continuous monitoring of firmware versions and timely patch deployment to satisfy the control objective of maintaining a robust vulnerability‑remediation process.
- Evidence of Due Diligence – Capturing patch‑status evidence provides a defensible audit trail that regulators and enterprise buyers increasingly demand.
- Defensible Audit Trail – Aligns with control objectives around secure software development and change management, supporting multiple frameworks (e.g., NIST CSF 2.0) with a single control evidence set.
Recommended Actions
- Inventory all Samsung devices in scope and record the current firmware / library version.
- Verify that Samsung’s security bulletin for CVE‑2025‑21042 has been applied; if not, prioritize patch rollout.
- Integrate the patch‑status check into your continuous control‑monitoring platform to generate immutable evidence of remediation.
- Update your vulnerability‑management policy to include native library checks for mobile device fleets.
- Document the remediation steps and retain logs for audit readiness.
