Adjacent-network memory disclosure via Media out-of-bounds read
Published Jun 4, 2026 · Updated Jun 4, 2026
Out-of-bounds read in Google Chrome Media before 149.0.7827.53 allows attackers to read process memory via malicious local-network traffic. Google identifies the Media component and an out-of-bounds memory read, but the restricted Chromium issue leaves the exact affected routine, faulty read operation, and traffic format undisclosed. Exploitation requires access to the same local network segment; the published impact is memory disclosure, with no reported write, code-execution, or availability effect.
