CVE-2023-28578

9.3 CRITICAL

📋 TL;DR

CVE-2023-28578 is a memory corruption vulnerability in Qualcomm Core Services that occurs when removing a single event listener. This allows attackers to potentially execute arbitrary code or cause denial of service on affected devices. The vulnerability affects Qualcomm chipsets used in smartphones, IoT devices, and other embedded systems.

💻 Affected Systems

Products:
  • Qualcomm chipsets with Core Services component
Versions: Multiple Qualcomm chipset versions prior to March 2024 security updates
Operating Systems: Android, Embedded Linux systems using Qualcomm chipsets
Default Config Vulnerable: ⚠️ Yes
Notes: Affects devices using vulnerable Qualcomm chipsets regardless of OEM implementation.

📦 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

Application crashes, denial of service, or limited privilege escalation within the affected service context.

🟢

If Mitigated

Contained service disruption without system-wide impact if proper sandboxing and privilege separation are implemented.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: HIGH

🎯 Exploit Status

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

Memory corruption vulnerabilities typically require specific conditions to trigger but can be exploited remotely if the affected service is exposed.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: March 2024 Qualcomm security updates

Vendor Advisory: https://www.qualcomm.com/company/product-security/bulletins/march-2024-bulletin

Restart Required: Yes

Instructions:

1. Check with device manufacturer for available security updates. 2. Apply March 2024 or later Qualcomm security patches. 3. Reboot device after patch installation. 4. Verify patch installation through system settings.

🔧 Temporary Workarounds

Disable unnecessary services

all

Reduce attack surface by disabling non-essential Qualcomm services if possible

Network segmentation

all

Isolate affected devices from untrusted networks

🧯 If You Can't Patch

  • Implement strict network access controls to limit exposure
  • Monitor for abnormal process behavior or crashes in Core Services

🔍 How to Verify

Check if Vulnerable:

Check device security patch level - if before March 2024, likely vulnerable. Check Qualcomm chipset version against advisory.

Check Version:

On Android: Settings > About phone > Android version > Security patch level

Verify Fix Applied:

Verify security patch level includes March 2024 or later Qualcomm updates in device settings.

📡 Detection & Monitoring

Log Indicators:

  • Unexpected crashes in Qualcomm services
  • Memory access violations in system logs
  • Abnormal process termination

Network Indicators:

  • Unusual network traffic to/from Qualcomm services
  • Connection attempts to unexpected ports

SIEM Query:

process_name:"qualcomm" AND (event_type:crash OR memory_violation)
