Could you build this?
No Discovering a Windows kernel/filesystem access-check bypass vulnerability and writing an exploit PoC requires deep Windows internals reverse engineering and low-level security research.
What it would actually take: Requires deep reverse engineering of Windows kernel drivers (specifically cflt.sys / Cloud Files API) and NTFS reparse point handling using IDA Pro or Ghidra. It involves understanding security token impersonation, file access check routines, and undocumented Win32/NT APIs, followed by constructing targeted C/C++ code that manipulates file placeholders to trigger unintended access bypasses.
