Description
MSI Afterburner v4.6.5.16370 is vulnerable to a Denial of Service vulnerability by triggering the 0x80002000 IOCTL code of the RTCore64.sys driver.
Vulnerability
The 0x80002000 IOCTL code of the RTCore64.sys driver allows to perform a Denial of Service, leading to a BSOD of the affected computer caused by a NULL pointer dereference. The handle to the driver can only be obtained from a high integrity process.
The prologue of the vulnerable function sub_11150 is:
At [1] value of second parameter on RDX register is assigned to RDI. The second parameter is a pointer to the SystemBuffer obtained from the IRP object (pIrp->AssociatedIrp.SystemBuffer) and it's controlled by the attacker in the lpInBuffer value on the IOCTL request call. At [2] the value is dereferenced without checking if it's a valid memory address, which result in a NULL pointer dereference when the attacker sends a NULL lpInputBuffer value:
