CVE-2024-21464
📋 TL;DR
This CVE describes a memory corruption vulnerability in Qualcomm's IPA (IP Accelerator) statistics processing when no active clients are registered. Successful exploitation could allow attackers to execute arbitrary code or cause denial of service on affected devices. This primarily affects devices using Qualcomm chipsets with vulnerable IPA implementations.

⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with kernel privileges leading to complete device compromise, data theft, or persistent backdoor installation.
Likely Case
Device crash/reboot causing denial of service, potentially requiring physical reset or factory restore.
If Mitigated
Limited impact with proper network segmentation and exploit mitigations, possibly resulting in service disruption without data compromise.
🎯 Exploit Status
Exploitation requires understanding of IPA statistics handling and memory corruption techniques. No public exploits known as of advisory publication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Qualcomm January 2025 security bulletin for specific patched versions
Vendor Advisory: https://docs.qualcomm.com/product/publicresources/securitybulletin/january-2025-bulletin.html
Restart Required: Yes
Instructions:
1. Check device manufacturer for firmware updates. 2. Apply Qualcomm-provided patches through OEM updates. 3. Reboot device after update installation. 4. Verify patch application through version checks.
🔧 Temporary Workarounds
Disable IPA statistics if unused
allIf IPA statistics functionality is not required, disable it to prevent the vulnerable code path from being triggered.
Specific commands depend on device configuration and OEM implementation
🧯 If You Can't Patch
- Network segmentation to restrict access to IPA services
- Implement exploit mitigations like ASLR and stack canaries if supported by platform
🔍 How to Verify
Check if Vulnerable:
Check device firmware version against Qualcomm's advisory and OEM security bulletinsCheck Version:
Device-specific commands vary by manufacturer (e.g., 'getprop ro.build.version.security_patch' on Android)Verify Fix Applied:
Verify firmware version has been updated to patched version specified by OEM📡 Detection & Monitoring
