Windows Hello bypass via cloned sensor identifier

Authentication bypass in ELAN Match-on-Chip FPR on Dell Inspiron allows physically proximate attackers to assume a Windows user's identity. The Match-on-Chip design exposes a valid sensor identifier to enumeration, then accepts that cloned identifier from a spoofed fingerprint sensor during Windows Hello recognition. Physical access, a spoof sensor, and user interaction are required; the result is Windows Hello account impersonation rather than remote compromise.
