CVE-2025-47332

6.7 MEDIUM

📋 TL;DR

This vulnerability involves memory corruption when processing configuration calls from userspace in Qualcomm components, potentially allowing local attackers to execute arbitrary code or cause denial of service. It affects systems with Qualcomm chipsets that have vulnerable drivers or firmware. The impact is limited to attackers with local access to the affected system.

💻 Affected Systems

Products:
  • Qualcomm chipsets with vulnerable drivers/firmware
Versions: Specific versions not detailed in reference; check Qualcomm advisory for affected chipset models and driver versions.
Operating Systems: Android, Linux-based systems using Qualcomm components
Default Config Vulnerable: ⚠️ Yes
Notes: Affects systems where Qualcomm drivers or firmware handle userspace configuration calls. Exact configurations depend on chipset integration.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Local privilege escalation to kernel mode, allowing complete system compromise and persistence.

🟠

Likely Case

Local denial of service (system crash) or limited information disclosure from kernel memory.

🟢

If Mitigated

No impact if proper access controls prevent unauthorized users from making configuration calls.

🌐 Internet-Facing: LOW - Requires local access to the system, not directly exploitable over network.
🏢 Internal Only: MEDIUM - Internal users with local access could exploit this for privilege escalation or DoS.

🎯 Exploit Status

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

Exploitation requires local access and knowledge of memory corruption techniques. No public exploit code is known at this time.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check Qualcomm security bulletin for specific patched driver/firmware versions.

Vendor Advisory: https://docs.qualcomm.com/product/publicresources/securitybulletin/january-2026-bulletin.html

Restart Required: Yes

Instructions:

1. Review Qualcomm security bulletin for affected chipset models. 2. Obtain updated drivers/firmware from device manufacturer or Qualcomm. 3. Apply patches according to vendor instructions. 4. Reboot system to load patched components.

🔧 Temporary Workarounds

Restrict userspace access

linux

Limit which users or processes can make configuration calls to vulnerable drivers.

Use SELinux/AppArmor policies to restrict access to Qualcomm driver interfaces.
Implement mandatory access controls on /dev nodes related to Qualcomm.

🧯 If You Can't Patch

  • Implement strict access controls to prevent unauthorized users from interacting with Qualcomm driver interfaces.
  • Monitor system logs for unusual configuration call patterns or memory corruption warnings.

🔍 How to Verify

Check if Vulnerable:

Check Qualcomm chipset model and driver versions against the security bulletin. Use 'lsmod | grep qualcomm' or similar to identify loaded Qualcomm modules.

Check Version:

For Linux: 'modinfo <qualcomm_module>' or check /sys/class/... for firmware versions. For Android: check build properties or vendor security patches.

Verify Fix Applied:

Verify that Qualcomm driver/firmware versions match patched versions listed in the advisory. Check system logs for absence of memory corruption errors after patch.

📡 Detection & Monitoring

Log Indicators:

  • Kernel panic logs mentioning Qualcomm drivers
  • Memory corruption warnings in dmesg or system logs
  • Unexpected process crashes related to configuration calls

Network Indicators:

  • None - this is a local vulnerability

SIEM Query:

Search for 'qualcomm' AND ('panic' OR 'corruption' OR 'oops') in kernel logs.
