CVE-2025-9319Network attack vector

Code execution via unverified remote download

Published Sep 11, 2025 · Updated Sep 11, 2025

Code execution in Lenovo Wallpaper Client 3.0.70.3301 and earlier allows remote attackers to run arbitrary code after user interaction. The client downloads and executes code without sufficiently verifying its origin or integrity, although Lenovo does not identify the affected function or download path. Exploitation requires an unspecified condition and active user interaction; successful code runs in the client's security context.
