CVE-2025-47330

Q: What is the severity of CVE-2025-47330?

CVE-2025-47330 has a CVSS score of 5.5 (MEDIUM). This vulnerability allows an attacker to cause a temporary denial of service (DoS) by sending specially crafted video packets to vulnerable systems. It affects devices using Qualcomm video firmware components. The impact is limited to service disruption rather than data compromise or system takeover.

5.5 MEDIUM

Denial of Service

📋 TL;DR

This vulnerability allows an attacker to cause a temporary denial of service (DoS) by sending specially crafted video packets to vulnerable systems. It affects devices using Qualcomm video firmware components. The impact is limited to service disruption rather than data compromise or system takeover.

💻 Affected Systems

Products:

Qualcomm video firmware components

Versions: Specific versions not detailed in reference; consult Qualcomm advisory for exact affected versions.

Operating Systems: Android, Linux-based systems using Qualcomm chipsets

Default Config Vulnerable: ⚠️ Yes

Notes: Affects systems with video processing enabled using vulnerable Qualcomm firmware. Mobile devices and embedded systems are primary targets.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system crash requiring reboot, disrupting video processing services and dependent applications.

🟠

Likely Case

Temporary video processing interruption causing glitches or freezes in video playback/streaming.

🟢

If Mitigated

Minor performance degradation with automatic recovery, minimal service impact.

🌐 Internet-Facing: MEDIUM

🏢 Internal Only: LOW

🎯 Exploit Status

Public PoC: ✅ No

Weaponized: UNKNOWN

Unauthenticated Exploit: ⚠️ Yes

Complexity: MEDIUM

Exploitation requires sending malformed video packets to the firmware interface. No authentication needed but requires network/system access.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Refer to Qualcomm January 2026 security bulletin for specific patched versions.

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

Restart Required: Yes

Instructions:

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

🔧 Temporary Workarounds

Network filtering

all

Block or filter suspicious video packet traffic at network boundaries.

Service isolation

all

Isolate video processing services from untrusted networks.

🧯 If You Can't Patch

Implement strict network segmentation to limit access to video processing components.
Monitor for abnormal video service crashes or restarts as exploitation indicators.

🔍 How to Verify

Check if Vulnerable:

Check device firmware version against Qualcomm advisory; vulnerable if using affected firmware versions.

Check Version:

Device-specific; typically 'cat /proc/version' or manufacturer-provided version check tools.

Verify Fix Applied:

Verify firmware version matches patched version in Qualcomm bulletin and test video processing functionality.

📡 Detection & Monitoring

Log Indicators:

Video service crashes, abnormal packet parsing errors in system logs
Frequent video process restarts

Network Indicators:

Unusual video packet patterns to video processing ports
Spike in malformed packet traffic

SIEM Query:

source="system_logs" AND ("video_firmware" OR "video_service") AND ("crash" OR "error" OR "restart")
