CVE-2022-30530
📋 TL;DR
This vulnerability in Intel DSA software allows authenticated local users to bypass protection mechanisms and potentially escalate privileges. It affects systems running Intel DSA software before version 22.4.26. The attacker must already have local authenticated access to the system.
💻 Affected Systems
- Intel(R) Driver & Support Assistant (DSA)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker gains full administrative/root privileges on the system, enabling complete system compromise, data theft, and persistence.
Likely Case
An authenticated user with limited privileges escalates to higher privileges, potentially accessing sensitive data or performing unauthorized administrative actions.
If Mitigated
With proper access controls and least privilege principles, the impact is limited as the attacker needs initial authenticated access.
🎯 Exploit Status
Exploitation requires authenticated local access; no public exploit code is known.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 22.4.26 or later
Vendor Advisory: http://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00725.html

🔧 Temporary Workarounds
Uninstall Intel DSA
allRemove the vulnerable software if not required.
On Windows: Control Panel > Programs > Uninstall Intel Driver & Support Assistant
On Linux: Use package manager to remove intel-dsa package
Restrict Local Access
allLimit authenticated user access to systems with Intel DSA installed.
🧯 If You Can't Patch
- Apply strict least privilege principles to limit authenticated user capabilities.
- Monitor systems for unusual privilege escalation attempts and audit local user activities.
🔍 How to Verify
Check if Vulnerable:
Check Intel DSA version in the application interface or via system information tools.Check Version:
On Windows: Check 'About' in Intel DSA GUI or registry. On Linux: Check package version via dpkg/rpm.Verify Fix Applied:
Confirm Intel DSA version is 22.4.26 or later after update.📡 Detection & Monitoring
Log Indicators:
- Unexpected privilege escalation events in system logs
- Intel DSA process spawning with elevated privileges
Network Indicators:
- Local privilege escalation does not typically generate network traffic
SIEM Query:
Search for events related to Intel DSA processes gaining elevated privileges or unusual access patterns.
