CVE‑2026‑91826: Samsung rlottie Stack‑based Buffer Overflow Enables Remote Code Execution
What It Is – Samsung’s open‑source rlottie animation library contains a stack‑based buffer overflow. The flaw arises from missing length checks on user‑supplied data before copying it to a fixed‑size stack buffer.
Exploitability – CVSS 7.8 (High). The vulnerability can be triggered by crafted data supplied to any application that loads rlottie. No authentication is required, and successful exploitation yields arbitrary code execution in the context of the vulnerable process.
Affected Products – Samsung rlottie library (all versions prior to the vendor‑released fix). The library is embedded in many Android, embedded‑device, and cross‑platform applications.
Why It Matters for Trust & Control Assurance
- Continuous monitoring of third‑party components is a core control objective; a single unpatched library can invalidate an organization’s evidence of secure software supply‑chain practices.
- Demonstrable due‑diligence (inventory, version tracking, patch status) provides a defensible audit trail across frameworks that map to the “secure software development” control.
- Enterprise buyers increasingly demand proof that all external libraries are assessed and remediated, not just the primary product stack.
Recommended Actions
- Identify every application and service that includes rlottie; verify version numbers against Samsung’s advisory.
- Apply the vendor‑provided patch or upgrade to a version that addresses CVE‑2026‑91826.
- Record remediation steps in your control‑mapping repository and capture evidence in the Trust Center for audit readiness.
- Integrate automated dependency scanning to flag future library vulnerabilities early.
