CVE-2024-33030

6.7 MEDIUM

📋 TL;DR

This CVE describes a memory corruption vulnerability in Qualcomm's IPC frequency table parameter parsing for LPLH (likely Low Power Low Hardware). When processing parameters larger than expected, it can cause buffer overflow or memory corruption. This affects devices using vulnerable Qualcomm chipsets, primarily mobile devices and IoT products.

💻 Affected Systems

Products:
  • Qualcomm chipsets with vulnerable IPC implementation
Versions: Specific chipset firmware versions not detailed in reference
Operating Systems: Android, Linux-based embedded systems
Default Config Vulnerable: ⚠️ Yes
Notes: Affects devices using Qualcomm chipsets with the vulnerable IPC component. Exact models depend on chipset firmware versions.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Remote code execution leading to complete device compromise, data theft, or persistent backdoor installation.

🟠

Likely Case

Device crash/reboot (denial of service) or limited information disclosure from memory corruption.

🟢

If Mitigated

System crash requiring manual reboot with no data loss if proper memory protections are enabled.

🌐 Internet-Facing: MEDIUM - Requires specific IPC communication to vulnerable component, not directly internet-exposed.
🏢 Internal Only: HIGH - Malicious apps or compromised processes could trigger the vulnerability locally.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Requires ability to send crafted IPC messages to the vulnerable component, typically from a compromised or malicious application.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Refer to Qualcomm November 2024 security bulletin for specific chipset firmware versions

Vendor Advisory: https://docs.qualcomm.com/product/publicresources/securitybulletin/november-2024-bulletin.html

Restart Required: Yes

Instructions:

1. Check Qualcomm advisory for affected chipset. 2. Obtain firmware update from device manufacturer. 3. Apply update following manufacturer instructions. 4. Reboot device.

🔧 Temporary Workarounds

Restrict IPC access

linux

Limit which processes can communicate with the vulnerable IPC component using SELinux/AppArmor policies

# Requires custom SELinux/AppArmor policy configuration
# Consult device manufacturer for specific implementation

🧯 If You Can't Patch

  • Isolate affected devices from untrusted networks
  • Implement application allowlisting to prevent malicious apps from accessing IPC

🔍 How to Verify

Check if Vulnerable:

Check device chipset firmware version against Qualcomm's November 2024 security bulletin

Check Version:

# Android: getprop ro.bootloader or check Settings > About phone
# Linux embedded: Check manufacturer firmware version

Verify Fix Applied:

Verify firmware version has been updated to patched version specified in Qualcomm advisory

📡 Detection & Monitoring

Log Indicators:

  • Kernel panic logs
  • IPC subsystem crash logs
  • Unexpected process termination

Network Indicators:

  • Unusual inter-process communication patterns

SIEM Query:

source="kernel" AND ("panic" OR "oops") AND component="ipc"
