CVE-2026-0139Network attack vector

Remote code execution via modem bounds-check omission

Published Jun 16, 2026 · Updated Jun 16, 2026

Out-of-bounds write in the Google Android modem allows remote authenticated users to execute arbitrary code through network input. Google identifies a missing bounds check in the modem, but the underlying function, input path, and overwrite target are not public. Low privileges are required, no user interaction is needed, and successful exploitation can compromise confidentiality, integrity, and availability.
