CVE-2025-11543Network attack vector

Unauthorized firmware execution via failed integrity validation

Published Dec 22, 2025 · Updated Dec 22, 2025

Improper firmware integrity validation in Sharp Display Solutions projectors allows remote attackers to install and run unauthorized firmware. The vendor identifies the firmware integrity check as the affected locus but does not disclose the precise verification operation that accepts untrusted firmware. Exploitation requires network access to a listed projector and unspecified prerequisite conditions, and successful exploitation replaces trusted device code.
