Local sensitive process-memory disclosure
Published Nov 10, 2025 · Updated Nov 10, 2025
Information disclosure in Google Chrome before 142.0.7444.59 on Windows allows local users to read sensitive process memory via a malicious file. Google identifies App-Bound Encryption as the affected component, but the restricted issue and public release advisory do not disclose how the file exposes memory. Exploitation requires local access and interaction with the malicious file; the published impact is limited to confidentiality.
