How CVE-2025-1006 Works
This vulnerability occurs due to improper memory management in Chrome’s Network component. When a crafted web app triggers a specific sequence of network operations, it leads to a use-after-free (UAF) condition. The browser fails to clear a freed memory pointer, allowing an attacker to corrupt the heap by manipulating the dangling reference. This could potentially enable remote code execution or browser crashes.
DailyCVE Form:
Platform: Google Chrome
Version: < 133.0.6943.126
Vulnerability: Use-After-Free
Severity: Medium
Date: 04/07/2025
What Undercode Say:
Exploitation Analysis:
1. Crafted web app forces premature object deallocation.
2. Attacker retains reference to freed memory.
3. Heap manipulation via controlled data.
Protection Measures:
1. Update Chrome to v133.0.6943.126+.
2. Enable sandboxing for network processes.
3. Apply strict Content Security Policy (CSP).
Detection Commands:
Check Chrome version: google-chrome --version | grep -q "133.0.6943.126" || echo "Vulnerable"
Exploit PoC (Conceptual):
// Hypothetical trigger (simplified) let maliciousObj = new NetworkRequest(); maliciousObj.forceEarlyFree(); maliciousObj.referenceFreedMemory();
Mitigation Code:
// Safe memory handling patch example
void NetworkComponent::fixUAF() {
if (dangling_ptr) {
dangling_ptr = nullptr; // Nullify freed pointer
}
}
Log Monitoring:
Check Chrome crash logs for UAF patterns: grep -i "heap corruption" /var/log/chrome/crash.log
Browser Flags for Hardening:
--enable-strict-site-isolation --no-unsafe-web-usb
