CVE-2026-0135Network attack vector

Remote code execution via unchecked modem read

Published Jun 16, 2026 · Updated Jun 16, 2026

Out-of-bounds read in the Android Modem allows remote attackers to execute code without privileges or user interaction. The Modem component reads beyond an input buffer because a required bounds check is missing, but the affected function and input format are undisclosed. Neither additional execution privileges nor user interaction are required; Google has not published which modem input reaches the faulty read.
