CVE-2025-6558 — AI Deep Analysis Summary

🚨 **Essence**: A critical input validation flaw in Google Chrome's ANGLE and GPU components. 📉 **Consequences**: Attackers can bypass the browser's security sandbox, leading to potential full system compromise.

🛡️ **Root Cause**: CWE-20 (Improper Input Validation). The browser fails to properly verify untrusted input before processing it in the GPU/ANGLE layers.

👥 **Affected**: Google Chrome versions **prior to 138.0.7204.157**. Specifically impacts the ANGLE graphics translation layer and GPU handling modules.

💀 **Impact**: Hackers can achieve **Sandbox Escape**. This elevates privileges from a restricted browser context to unrestricted system access, risking data theft or malware installation.

⚡ **Threshold**: **Low**. Exploitation typically requires only visiting a malicious webpage or triggering a specific GPU rendering path. No authentication needed.

🔓 **Exploits**: **Yes**. Public PoCs and exploits are available on GitHub (e.g., `allinsthon/CVE-2025-6558-exp`). Wild exploitation risk is high.

🔍 **Check**: Scan for Chrome versions < 138.0.7204.157. Look for active GPU/ANGLE usage in logs. Use vulnerability scanners detecting sandbox escape patterns.

✅ **Fix**: **Yes**. Official patch released in Chrome **138.0.7204.157**. Update immediately via Chrome's auto-update mechanism or manual download.

🚧 **No Patch?**: Disable GPU hardware acceleration in Chrome settings (`chrome://settings/system`). Restrict browser permissions. Use network-level filtering.

🔥 **Urgency**: **CRITICAL**. Due to sandbox escape nature and public exploits, prioritize patching immediately. High risk of active exploitation.
