CVE-2025-52539

7.3 HIGH

📋 TL;DR

A buffer overflow vulnerability in Xilinx Run Time Environment allows local attackers to read or corrupt data from the advanced extensible interface (AXI). This could lead to loss of confidentiality, integrity, and availability of affected systems. Users of Xilinx/AMD FPGA platforms with the vulnerable runtime environment are affected.

💻 Affected Systems

Products:
  • Xilinx Run Time Environment
Versions: Specific versions not detailed in provided reference; consult AMD advisory for exact affected versions.
Operating Systems: Linux-based systems running Xilinx/AMD FPGA platforms
Default Config Vulnerable: ⚠️ Yes
Notes: Affects systems using Xilinx Run Time Environment with AXI interfaces. Exact product versions should be verified against AMD advisory.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise allowing privilege escalation, data exfiltration, or denial of service through AXI interface manipulation.

🟠

Likely Case

Local privilege escalation allowing attackers to read sensitive data or disrupt system operations.

🟢

If Mitigated

Limited impact if proper access controls and isolation prevent local attackers from reaching vulnerable components.

🌐 Internet-Facing: LOW - This is a local vulnerability requiring attacker access to the system.
🏢 Internal Only: HIGH - Local attackers on shared systems or compromised accounts could exploit this vulnerability.

🎯 Exploit Status

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

Requires local access and knowledge of buffer overflow exploitation techniques. No public exploit code identified in initial advisory.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check AMD advisory for specific patched versions

Vendor Advisory: https://www.amd.com/en/resources/product-security/bulletin/AMD-SB-8014.html

Restart Required: Yes

Instructions:

1. Review AMD advisory AMD-SB-8014. 2. Identify affected Xilinx Run Time Environment versions. 3. Apply vendor-provided patches or updates. 4. Restart affected systems to complete installation.

🔧 Temporary Workarounds

Restrict local access

all

Limit local user access to systems running vulnerable Xilinx Run Time Environment

Isolate FPGA systems

all

Segment networks and restrict access to systems with FPGA components

🧯 If You Can't Patch

  • Implement strict access controls to prevent unauthorized local access to affected systems
  • Monitor systems for unusual AXI interface activity or buffer overflow attempts
