CVE-2024-48869
📋 TL;DR
This vulnerability allows a privileged user on affected Intel Xeon 6 processors with E-cores to potentially escalate privileges via local access when using Intel TDX or SGX security features. The issue stems from improper restriction of software interfaces to hardware features. Only systems with these specific Intel processors and security extensions enabled are affected.
💻 Affected Systems
- Intel Xeon 6 processors with E-cores
⚠️ 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
A privileged attacker could gain higher privileges than intended, potentially compromising the entire system, accessing sensitive data protected by TDX/SGX enclaves, or bypassing security boundaries.
Likely Case
A local administrator or compromised privileged account could escalate privileges to access protected memory regions or security enclaves they shouldn't have access to.
If Mitigated
With proper access controls and monitoring, the impact is limited to potential privilege boundary violations within the affected hardware security features.
🎯 Exploit Status
Exploitation requires local privileged access and knowledge of the hardware security interfaces. No public exploits have been reported.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Microcode updates via BIOS/UEFI firmware
Vendor Advisory: https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01268.html
Restart Required: Yes
Instructions:
1. Check with your system manufacturer for BIOS/UEFI updates. 2. Apply the firmware update following manufacturer instructions. 3. Reboot the system to load updated microcode.
🔧 Temporary Workarounds
Disable Intel TDX/SGX
allDisable the affected security features if not required for your workload
Check BIOS/UEFI settings for TDX and SGX options and disable them
🧯 If You Can't Patch
- Restrict local privileged access to affected systems
- Implement strict monitoring and logging of privileged user activities
🔍 How to Verify
Check if Vulnerable:
Check processor model and microcode version. On Linux: cat /proc/cpuinfo | grep 'model name' and dmesg | grep microcodeCheck Version:
Linux: grep microcode /proc/cpuinfo; Windows: wmic cpu get caption,description,steppingVerify Fix Applied:
Verify microcode version after BIOS update matches patched version from manufacturer📡 Detection & Monitoring
Log Indicators:
