CVE-2026-0164Network attack vector

Remote code execution via unchecked modem write

Published Jun 16, 2026 · Updated Jun 16, 2026

Out-of-bounds write in Android kernel Modem allows remote attackers to execute code via unspecified vectors without user interaction. The Modem component fails to apply a required bounds check before writing data, allowing the write to extend beyond its destination buffer. Google has not disclosed the affected function or input format; successful exploitation executes code on the device without additional execution privileges.
