CVE-2025-11542Network attack vector

Unauthenticated command execution via stack buffer overflow

Published Dec 22, 2025 · Updated Dec 22, 2025

Stack-based buffer overflow in listed Sharp Display Solutions projector firmware allows remote attackers to execute arbitrary commands and programs. The vendor has not disclosed the affected request handler or which untrusted network input is copied beyond a stack buffer. No privileges or user interaction are required, but exploitation depends on an unspecified runtime condition and can compromise the projector's confidentiality, integrity, and availability.
