| 제목 | SOKNO S.R.L Speedfan 4.52 Memory Leak |
|---|
| 설명 | The driver of Speedfan speedfan.sys doesn't control MSR index when read it, That's why Security Researchers can leak memory using read c0000082 -LSTAR index , which the index holds address of KiSystemCall64 . During some research I found the offset of the KiSystemCall64 function 0x006BDE40 , When subtract it we can retrieve the base address of ntoskrnl.exe. This process causes the defeat of kASLR(kernel Address Space Layout Randomization). |
