CVE-2024-36242
📋 TL;DR
A protection mechanism failure in Intel's Software Protection Platform (SPP) for certain processors allows authenticated local users to potentially escalate privileges. This affects systems with specific Intel processors where SPP is enabled, potentially allowing attackers to bypass security controls.
💻 Affected Systems
- Intel processors with SPP technology
⚠️ 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).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker could gain full system control, access sensitive data, install persistent malware, or compromise other systems on the network.
Likely Case
Privileged users or attackers who gain initial access could elevate privileges to perform unauthorized actions, access restricted data, or maintain persistence.
If Mitigated
With proper access controls, monitoring, and network segmentation, impact is limited to isolated systems with minimal data exposure.
🎯 Exploit Status
Requires local authenticated access and knowledge of SPP implementation details. No public exploits known at this time.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Microcode updates and BIOS/UEFI firmware updates
Vendor Advisory: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-01196.html
Restart Required: Yes
Instructions:
1. Check Intel advisory for affected processor models. 2. Contact system/device manufacturer for BIOS/UEFI updates. 3. Apply microcode updates through OS vendor patches. 4. Reboot system after updates.
🔧 Temporary Workarounds
Disable SPP if not required
allDisable Software Protection Platform feature if not needed for your use case
Check BIOS/UEFI settings for SPP/Platform Security features
Restrict local access
allImplement strict access controls and least privilege for local user accounts
🧯 If You Can't Patch
- Implement strict access controls and monitor for privilege escalation attempts
- Segment affected systems and limit lateral movement capabilities
🔍 How to Verify
Check if Vulnerable:
Check processor model and microcode version. Use 'cat /proc/cpuinfo' on Linux or system information tools on Windows.Check Version:
Linux: 'dmesg | grep microcode' or 'cat /proc/cpuinfo', Windows: 'wmic cpu get name,description,stepping'Verify Fix Applied:
Verify microcode version matches patched version from vendor. Check BIOS/UEFI version is updated.📡 Detection & Monitoring
Log Indicators:
- Unexpected privilege escalation events
- Unauthorized access to protected memory regions
- Suspicious SPP-related operations
Network Indicators:
- Lateral movement from affected systems
- Unexpected outbound connections post-exploitation
