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.
Docker Desktop allows local privilege escalation to NT AUTHORITY\SYSTEM because it mishandles the collection of diagnostics with Administrator privileges, leading to arbitrary DACL permissions overwrites and arbitrary file writes. This affects Docker Desktop Enterprise before 2.1.0.9, Docker Desktop for Windows Stable before 2.2.0.4, and Docker Desktop for Windows Edge before 2.2.2.0.
