DescriptionCVE.org

An issue was discovered in Samsung Mobile Processor Exynos 1380. The lack of a length check leads to out-of-bounds writes.

Executive ViewAI

Why It Matters

A critical vulnerability in Samsung's Exynos 1380 processor enables remote code execution through memory corruption, affecting millions of Galaxy devices globally. Without an available patch, organizations with Samsung device deployments face immediate risk of unauthorized system access and data compromise.

Business Impact: Severe

Compensating Controls

Isolate affected devices on separate network segments with restricted access to critical systems; implement strict application whitelisting and disable debugging interfaces; enforce maximum privilege restrictions and enhanced endpoint detection; monitor for exploitation indicators; consider staged device replacement until official patch is available; restrict device usage to non-sensitive functions where feasible.

Attack Technique

Buffer Overflow HIGH

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
