CVE-2024-47024
📋 TL;DR
This vulnerability is an integer overflow in the virtio_ring.h header file that allows local privilege escalation without user interaction. It affects Android devices using vulnerable virtio implementations, potentially allowing attackers to gain root access from a limited user context.
💻 Affected Systems
- Android
- Pixel devices
- Devices using virtio implementations
📦 What is this software?
Android by Google
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with root privileges, allowing complete control over the device, data exfiltration, and persistence mechanisms.
Likely Case
Local privilege escalation from a limited user or app context to root/system privileges on affected Android devices.
If Mitigated
Limited impact if SELinux policies or other mandatory access controls prevent successful exploitation despite the vulnerability.
🎯 Exploit Status
Requires local access but no additional execution privileges. The integer overflow leads to out-of-bounds write.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: October 2024 Android Security Patch
Vendor Advisory: https://source.android.com/security/bulletin/pixel/2024-10-01
Restart Required: Yes
Instructions:
1. Apply October 2024 Android Security Patch. 2. For Pixel devices: Settings > System > System update > Check for update. 3. For other Android devices: Check manufacturer's security update schedule. 4. Reboot device after update.
🔧 Temporary Workarounds
Restrict local access
allLimit physical and logical access to devices to prevent local exploitation
🧯 If You Can't Patch
- Isolate affected devices from sensitive networks and data
- Implement strict application whitelisting and privilege separation
🔍 How to Verify
Check if Vulnerable:
Check Android security patch level: Settings > About phone > Android security patch level. If before October 2024, device is vulnerable.Check Version:
adb shell getprop ro.build.version.security_patchVerify Fix Applied:
Verify Android security patch level shows October 2024 or later after applying update.📡 Detection & Monitoring
Log Indicators:
- Kernel panic logs
- Unexpected privilege escalation attempts
- Memory corruption events in system logs
Network Indicators:
- None - this is a local exploit
SIEM Query:
Look for privilege escalation events or kernel panic logs from Android devices with pre-October 2024 patch levels
