CVE-2025-10495Hinoki check available

Adjacent-network code execution via improper certificate validation

Published Nov 12, 2025 · Updated Nov 12, 2025

Improper certificate validation in four Lenovo Windows clients allows remote attackers to execute arbitrary code from the same logical network. The published record does not identify the connection or certificate-validation code that accepts untrusted network input. Exploitation requires access to the endpoint's logical network and a specific, undisclosed condition; successful attacks run code on the endpoint.
