In PowerStrip version 3.90.736 and earlier, the driver's IOCTL dispatcher exposes code 0x80002008, which maps caller-supplied physical memory directly into the requesting user-mode process and returns the mapped virtual base address, giving a local user an arbitrary physical read/write primitive. Public exploitation of CVE-2026-29923 uses this to scan physical memory for the EPROCESS 'Proc' pool tag, copy the SYSTEM process token, and overwrite the caller's token to escalate to NT AUTHORITY\\SYSTEM.","Usecase":"Arbitrary physical memory read/write from user mode, abused for local privilege escalation to SYSTEM via token theft.","Privileges":"User","OperatingSystem":"Windows 10,
