Gửi #866833: SOKNO S.R.L Speedfan 4.52 Memory Leakthông tin

tiêu đềSOKNO S.R.L Speedfan 4.52 Memory Leak
Mô tảThe 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).
