CVE-2025-20018

8.4 HIGH

📋 TL;DR

This vulnerability in Intel Graphics Drivers allows an authenticated local user to potentially escalate privileges by exploiting an untrusted pointer dereference. It affects systems with vulnerable Intel graphics drivers installed. Attackers could gain higher system privileges than originally granted.

💻 Affected Systems

Products:
  • Intel Graphics Drivers
Versions: Specific versions not detailed in advisory; check Intel SA-01259 for exact affected versions
Operating Systems: Windows, Linux, Potentially other OS with Intel graphics support
Default Config Vulnerable: ⚠️ Yes
Notes: Requires Intel graphics hardware and vulnerable driver version. Systems without Intel graphics or with updated drivers are not 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).

⚠️ Risk & Real-World Impact

🔴

Worst Case

Full system compromise with administrative/root privileges, allowing complete control over the affected system and potential lateral movement.

🟠

Likely Case

Local privilege escalation from standard user to administrator/root, enabling installation of malware, data theft, or persistence mechanisms.

🟢

If Mitigated

Limited impact with proper privilege separation and minimal user access, though still concerning for multi-user systems.

🌐 Internet-Facing: LOW - Requires local authenticated access, not directly exploitable over network.
🏢 Internal Only: HIGH - Significant risk for multi-user systems, shared workstations, or environments where users have local access.

🎯 Exploit Status

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

Requires authenticated local access and knowledge of exploitation techniques. CVSS 8.4 indicates significant impact but requires local access.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check Intel DSA or Windows Update for latest graphics driver versions

Vendor Advisory: https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01259.html

Restart Required: Yes

Instructions:

1. Visit Intel Driver & Support Assistant (DSA) or Windows Update. 2. Check for graphics driver updates. 3. Download and install latest Intel graphics driver. 4. Restart system to complete installation.

🔧 Temporary Workarounds

Restrict local user access

all

Limit local user accounts and implement least privilege principles to reduce attack surface

Disable unnecessary graphics features

all

Reduce attack surface by disabling unused graphics capabilities if possible

🧯 If You Can't Patch

  • Implement strict access controls and limit local user privileges
  • Monitor for suspicious privilege escalation attempts and unauthorized administrative activities

🔍 How to Verify

Check if Vulnerable:

Check Intel graphics driver version against affected versions listed in Intel SA-01259 advisory

Check Version:

Windows: dxdiag (Display tab) or Device Manager > Display adapters. Linux: lspci -v | grep -A 12 VGA

Verify Fix Applied:

Verify graphics driver version is updated to patched version from Intel DSA or Windows Update

📡 Detection & Monitoring

Log Indicators:

  • Unexpected privilege escalation events
  • Suspicious graphics driver process behavior
  • Failed privilege escalation attempts
