CVE-2025-25216
📋 TL;DR
An improper input validation vulnerability in certain Intel Graphics Drivers and Intel LTS kernels allows unprivileged local users to cause denial of service. Attackers with authenticated access and specific internal knowledge can potentially crash affected systems via low-complexity attacks. This affects systems running vulnerable Intel graphics firmware and LTS kernels.
💻 Affected Systems
- Intel Graphics Drivers
- Intel LTS kernels
⚠️ 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).

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
System crash or kernel panic requiring physical reboot, disrupting all services on the affected machine.
Likely Case
Local denial of service affecting graphics functionality or system stability for the current user session.
If Mitigated
Minimal impact with proper access controls limiting local user privileges and network segmentation.
🎯 Exploit Status
Attack requires authenticated local access and specific internal knowledge of vulnerable components.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Intel SA-01356 for specific driver and kernel versions
Vendor Advisory: https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01356.html
Restart Required: Yes
Instructions:
1. Review Intel SA-01356 advisory. 2. Identify affected driver/kernel versions. 3. Update to patched versions via vendor channels. 4. Reboot system after update.
🔧 Temporary Workarounds
Restrict local user privileges
allLimit local user accounts to prevent exploitation by unprivileged users
Disable vulnerable kernel modules
linuxBlacklist or disable specific Intel graphics kernel modules if not required
echo 'blacklist [module_name]' >> /etc/modprobe.d/blacklist.conf
update-initramfs -u
🧯 If You Can't Patch
- Implement strict access controls to limit local user privileges
- Segment affected systems from critical infrastructure to contain potential DoS impact
🔍 How to Verify
Check if Vulnerable:
Check Intel SA-01356 for affected versions and compare with system's Intel driver and kernel versionsCheck Version:
Linux: 'uname -r' for kernel, 'modinfo [intel_graphics_module]' for driver; Windows: Device Manager > Display adapters > Properties > Driver versionVerify Fix Applied:
Verify installed driver/kernel versions match patched versions listed in Intel advisory📡 Detection & Monitoring
