Null Pointer Dereference in MSI Dragon Center NTIOLib_X64.sys IOCTL Handler

IdentifiersCVE-2024-12227CWE-476· NULL Pointer Dereference

CVE-2024-12227 is a null pointer dereference vulnerability in the function MmUnMapIoSpace within the NTIOLib_X64.sys driver, part of the IOCTL handler in MSI Dragon Center versions up to 2.0.146.0. The vulnerability can be triggered locally, potentially causing the driver to dereference a null pointer when handling certain IOCTL requests.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Exploitation of this vulnerability can lead to a denial of service (system crash or BSOD) on the local host. There is no indication of privilege escalation or code execution, but the system's stability and availability are affected.

Mitigation

If you can’t patch tonight, do this now.

If immediate upgrade is not possible, restrict local access to the system to trusted users only, and consider disabling or uninstalling the affected driver until a patched version can be deployed.

Remediation

Patch, then assume compromise.

Upgrade MSI Dragon Center to version 2.0.148.0 or later, which addresses the null pointer dereference in the NTIOLib_X64.sys driver.

POC-CVE-2024-12227MaturityPoCVerified exploit

This repository contains a proof-of-concept (PoC) exploit for CVE-2024-12227, a null pointer dereference vulnerability in the MSI Dragon Center's NTIOLib_X64.sys driver (version 3.0.0.10) on Windows. The repository consists of a Python script (CVE-2024-12227.py) and a README.md. The exploit script uses the Windows ctypes library to interact with the vulnerable driver via its device file (\\.\NTIOLib_MysticLight), sending specific IOCTL codes to trigger the vulnerable code path. If the driver mishandles a failed memory mapping, it will dereference a NULL pointer, causing a Blue Screen of Death (BSOD). The exploit requires local administrator privileges and is only effective on systems with the specific vulnerable driver version. The README provides detailed background, usage instructions, and references. No network endpoints are involved; the attack vector is local, targeting a device driver interface.
