| Title | MSI MSI Dragon Center 2.0.146.0 NULL Pointer Dereference |
|---|
| Description | NTIOLib_X64.sys allows all users in Everyone Group to interact with it. When process IOCTL 0xC3506140, it doen't check the return value of MmMapIoSpace, then calls MmUnMapIoSpace directly with the return value of MmMapIoSpace. If MmMapIoSpace returns with NULL, call MmUnMapIoSpace with parameter address zero (NULL) will cause a BSOD in Windows System. |
