CVE-2025-48508
📋 TL;DR
This vulnerability allows a privileged attacker within a guest virtual machine to manipulate GPU hardware reset operations, potentially causing host system crashes or GPU resets leading to denial of service. It affects systems using AMD GPU hardware with vulnerable GFX IP blocks in virtualized environments.
💻 Affected Systems
- AMD GPU hardware with GFX IP blocks
⚠️ 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.

⚠️ Risk & Real-World Impact
Worst Case
Complete host system crash or persistent GPU failure requiring physical intervention to restore service.
Likely Case
Temporary denial of service affecting GPU-dependent applications and virtual machines.
If Mitigated
Limited impact with proper isolation and monitoring, potentially minor service disruption.
🎯 Exploit Status
Requires privileged access within guest VM and specific hardware configuration
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to AMD advisory for specific firmware/driver versions
Vendor Advisory: https://www.amd.com/en/resources/product-security/bulletin/AMD-SB-6024.html
Restart Required: Yes
Instructions:
1. Review AMD advisory for affected products. 2. Download updated firmware/drivers from AMD. 3. Apply updates following vendor instructions. 4. Reboot affected systems.
🔧 Temporary Workarounds
Disable GPU passthrough
allPrevent GPU hardware access from guest VMs
# For libvirt: remove <hostdev> GPU passthrough configuration
# For VMware: disable GPU passthrough in VM settings
Restrict VM privileges
allLimit privileged operations within guest VMs
# Use VM security policies to restrict hardware access
# Implement least privilege for VM users
🧯 If You Can't Patch
- Isolate affected systems from critical production environments
- Implement strict monitoring for GPU reset events and system crashes
🔍 How to Verify
Check if Vulnerable:
Check AMD advisory for specific product identification and compare with system hardware/driver versionsCheck Version:
# Linux: lspci -v | grep -i amd && cat /sys/class/drm/card*/device/ueventVerify Fix Applied:
Verify updated firmware/driver versions match those listed in AMD advisory as patched📡 Detection & Monitoring
Log Indicators:
- GPU reset events in system logs
- Unexpected VM crashes or host reboots
- Hardware error messages related to GPU
Network Indicators:
- Sudden loss of GPU-dependent services
