MSI Ambient Link Local Privilege Escalation Exploit

Multiple stack buffer overflows were found in the MSI AmbientLink MsIo64 driver when processing IoControlCode (IOCTL) 0x80102040, 0x80102044, 0x80102050, 0x80102054. Local attackers, including low integrity processes, can exploit these vulnerabilities and consequently gain NT AUTHORITY\SYSTEM privileges.
