CVE-2025-20648
📋 TL;DR
This vulnerability in MediaTek's APU (AI Processing Unit) allows an attacker to read memory beyond allocated bounds without requiring user interaction or elevated privileges. It could disclose sensitive information from the device's memory. Affected systems include devices using vulnerable MediaTek chipsets with the APU component.

⚠️ Risk & Real-World Impact
Worst Case
Sensitive kernel memory or process data could be leaked, potentially exposing cryptographic keys, authentication tokens, or other protected information.
Likely Case
Limited information disclosure from adjacent memory regions, possibly exposing non-critical system data or application information.
If Mitigated
No information disclosure occurs due to proper patching or security controls that prevent memory access.
🎯 Exploit Status
Exploitation requires local access and knowledge of memory layout. No authentication bypass needed but requires ability to execute code on the device.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to MediaTek security bulletin for specific firmware versions
Vendor Advisory: https://corp.mediatek.com/product-security-bulletin/March-2025
Restart Required: Yes
Instructions:
1. Check MediaTek security bulletin for affected chipset models. 2. Contact device manufacturer for firmware updates. 3. Apply firmware update containing patch ID ALPS09456673. 4. Reboot device after update.
🔧 Temporary Workarounds
Restrict local application execution
allLimit installation of untrusted applications to reduce attack surface
🧯 If You Can't Patch
- Implement strict application allowlisting to prevent untrusted code execution
- Monitor for suspicious local process activity and memory access patterns
🔍 How to Verify
Check if Vulnerable:
Check device chipset information and compare against MediaTek's affected products list in the security bulletinCheck Version:
Device-specific commands vary by manufacturer; typically check Settings > About Phone > Build Number or use 'getprop' commands on AndroidVerify Fix Applied:
Verify firmware version includes patch ID ALPS09456673 or check with device manufacturer for patched firmware confirmation📡 Detection & Monitoring
Log Indicators:
- Unusual memory access patterns in kernel logs
- APU driver error messages indicating boundary violations
Network Indicators:
- None - this is a local vulnerability
SIEM Query:
Search for kernel logs containing 'APU', 'bounds check', or memory access errors from MediaTek drivers
