SmartScreen is the OS-level malicious-code inspection and blocking mechanism whose bypass is the direct effect of CVE-2023-36025.
Microsoft's security update directly patches the SmartScreen flaw that permits the documented bypass.
Integrity verification of downloaded files and executables can still detect or block content that evades the bypassed SmartScreen check.
