CVE-2025-48510
📋 TL;DR
An improper return value vulnerability in AMD uProf allows local attackers to bypass Kernel Security Lockdown Restrictions (KSLR), potentially enabling unauthorized access to sensitive system information or causing denial of service. This affects users running vulnerable versions of AMD uProf software on their systems.
💻 Affected Systems
- AMD uProf
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through privilege escalation, allowing attackers to access sensitive kernel data, modify system configurations, or crash the system.
Likely Case
Local attackers bypass security restrictions to read protected kernel memory, potentially exposing sensitive information like encryption keys or credentials.
If Mitigated
Limited impact with proper access controls and monitoring, though some information disclosure may still occur.
🎯 Exploit Status
Exploitation requires local access and understanding of AMD uProf's internal workings. No public exploit code is currently available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check AMD advisory for specific patched version
Vendor Advisory: https://www.amd.com/en/resources/product-security/bulletin/AMD-SB-9019.html
Restart Required: Yes
Instructions:
1. Visit AMD security advisory page. 2. Download latest AMD uProf version. 3. Uninstall current version. 4. Install updated version. 5. Restart system.
🔧 Temporary Workarounds
Restrict uProf Access
allLimit which users can run AMD uProf to reduce attack surface
Disable uProf Service
allStop and disable uProf service if not required
sudo systemctl stop amduprof (Linux)
sc stop "AMD uProf Service" (Windows)
🧯 If You Can't Patch
- Implement strict access controls to limit who can run AMD uProf
- Monitor for unusual uProf process activity and kernel access attempts
🔍 How to Verify
Check if Vulnerable:
Check AMD uProf version against advisory. Run: amduprof --version (Linux) or check program properties (Windows)Check Version:
amduprof --versionVerify Fix Applied:
Verify installed version matches patched version from AMD advisory📡 Detection & Monitoring
Log Indicators:
- Unusual uProf process activity
- Failed KSLR enforcement attempts
- Unexpected kernel memory access
