CVE-2024-25576
📋 TL;DR
This vulnerability allows a privileged user on affected Intel FPGA systems to escalate their privileges through improper access control in firmware. It affects users of specific Intel FPGA products with firmware versions before 24.1. The issue requires local access to the system.
💻 Affected Systems
- Intel FPGA products with vulnerable firmware
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
A privileged user could gain full system control, potentially compromising the entire FPGA configuration and host system.
Likely Case
Privileged users could bypass intended access controls to modify FPGA configurations or access restricted system resources.
If Mitigated
With proper access controls and monitoring, impact is limited to authorized users attempting privilege escalation.
🎯 Exploit Status
Requires existing privileged access to the system; exploitation details not publicly disclosed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 24.1 or later
Vendor Advisory: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-01087.html
Restart Required: Yes
Instructions:
1. Download firmware version 24.1 or later from Intel's support site. 2. Follow Intel's firmware update procedures for your specific FPGA product. 3. Reboot the system after firmware update.
🔧 Temporary Workarounds
Restrict local access
allLimit physical and remote local access to systems with vulnerable FPGA hardware
Monitor privileged user activity
allImplement enhanced monitoring and logging for privileged user actions on FPGA systems
🧯 If You Can't Patch
- Implement strict access controls and least privilege principles for all users
- Monitor system logs for unusual privileged user activity or firmware access attempts
🔍 How to Verify
Check if Vulnerable:
Check FPGA firmware version using Intel's management tools or system BIOS/UEFI interfaceCheck Version:
Specific commands vary by FPGA product; consult Intel documentation for your hardwareVerify Fix Applied:
Verify firmware version shows 24.1 or later after update📡 Detection & Monitoring
