Local process-memory disclosure via out-of-bounds read
Published Jun 17, 2026 · Updated Jun 17, 2026
Out-of-bounds read in Chromoting in Google Chrome before 149.0.7827.155 allows local users on Windows to read process memory via a malicious file. Google has not disclosed the affected Chromoting function, buffer, or parsing operation that reads beyond its intended bounds. Exploitation requires a user to open the malicious file, and the documented consequence is limited to disclosure of potentially sensitive process memory.
