CVE-2025-52538

8.0 HIGH

📋 TL;DR

An integer overflow vulnerability in the XOCL driver allows local attackers to potentially read sensitive memory or crash systems. This affects systems using AMD XOCL drivers with improper input validation. Only local attackers with existing access can exploit this vulnerability.

💻 Affected Systems

Products:
  • AMD XOCL (Xilinx OpenCL) driver
Versions: Specific versions not detailed in reference; check AMD advisory for affected versions
Operating Systems: Linux systems using AMD XOCL drivers
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects systems with AMD XOCL driver installed and loaded. Virtualization environments using these drivers may be affected.

⚠️ 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

Local privilege escalation leading to full system compromise, sensitive data exposure, or complete system crash.

🟠

Likely Case

Local denial of service through system crash or kernel panic, potentially allowing limited information disclosure.

🟢

If Mitigated

Minimal impact if proper access controls limit local user privileges and systems are isolated.

🌐 Internet-Facing: LOW - Requires local access, cannot be exploited remotely.
🏢 Internal Only: MEDIUM - Malicious insiders or compromised local accounts could exploit this vulnerability.

🎯 Exploit Status

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

Requires local access and knowledge of driver interaction. Integer overflow exploitation typically requires specific conditions to be useful.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check AMD advisory for specific patched driver versions

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

Restart Required: Yes

Instructions:

1. Visit AMD security advisory. 2. Identify affected driver version. 3. Download and install patched driver from AMD. 4. Reboot system to load new driver.

🔧 Temporary Workarounds

Restrict driver access

linux

Limit which users can access the XOCL driver device files

chmod 600 /dev/xocl*
chown root:root /dev/xocl*

Unload driver module

linux

Temporarily disable the XOCL driver if not required

rmmod xocl
modprobe -r xocl

🧯 If You Can't Patch

  • Implement strict access controls to limit local user privileges
  • Isolate affected systems from critical networks and data

🔍 How to Verify

Check if Vulnerable:

Check installed XOCL driver version against AMD advisory: lsmod | grep xocl and check driver version

Check Version:

modinfo xocl | grep version

Verify Fix Applied:

Verify patched driver version is installed and loaded: modinfo xocl | grep version

📡 Detection & Monitoring

Log Indicators:

  • Kernel panic logs
  • Driver crash messages in dmesg
  • Unusual XOCL driver access patterns

Network Indicators:

  • None - local exploit only

SIEM Query:

Search for: 'xocl driver crash' OR 'kernel panic' AND source contains affected hostname
