CVE-2025-21042 — AI Deep Analysis Summary

🚨 **Essence**: Critical Remote Code Execution (RCE) in Samsung's image processing library (`libimagecodec.quram.so`). 💥 **Consequences**: Out-of-bounds write allows attackers to execute arbitrary code remotely via malici…

🔍 **Root Cause**: Out-of-bounds write (OOB Write) flaw. 📉 **CWE**: Not explicitly mapped in data, but technically an OOB Write vulnerability in the image codec library.

📱 **Affected**: Samsung Mobile Devices (Galaxy Android devices). 📦 **Component**: `libimagecodec.quram.so` (Samsung Image Codec). 📅 **Versions**: Prior to SMR Apr-2025 Release 1.

🕵️ **Attacker Actions**: Execute arbitrary code remotely. 🔓 **Privileges**: High impact (CVSS: H/C/I/H/A).…

⚖️ **Threshold**: Low. 🔑 **Auth**: None required (PR:N). 🖱️ **User Interaction**: Required (UI:R) — victim must open/view the malicious image. 🌐 **Network**: Remote (AV:N). ⚡ **Complexity**: Low (AC:L).…

🔓 **Public Exp**: Yes. 📂 **PoCs Available**: Multiple GitHub repositories exist (e.g., `B1ack4sh/Blackash-CVE-2025-21042`). 🌍 **Wild Exploitation**: Risk is high due to low complexity and remote nature.

🔎 **Self-Check**: Scan for presence of `libimagecodec.quram.so` on Android devices. 📋 **Indicator**: Check if device SMR patch level is **before** Apr-2025 Release 1. 🛠️ **Tools**: Use mobile security scanners or check s…

✅ **Fixed**: Yes. 🩹 **Patch**: Samsung Security Update (SMR) for **Apr-2025 Release 1** or later. 🔗 **Ref**: [Samsung Security Update](https://security.samsungmobile.com/securityUpdate.smsb?year=2025&month=04)

🛡️ **No Patch Workaround**: 1. 🚫 **Avoid** opening unknown/untrusted image files (especially DNG). 2. 📵 **Disable** auto-preview of images from untrusted sources. 3. 🔄 **Update** OS immediately if patch is available. 4.…

🔥 **Priority**: **CRITICAL**. ⏳ **Urgency**: Immediate action required. 📢 **Reason**: Remote code execution with low exploitation complexity. High impact on confidentiality, integrity, and availability.…
