CVE-2026-0159Network attack vector

Remote code execution via unchecked modem write

Published Sep 15, 2026 · Updated Sep 15, 2026

Out-of-bounds write in Android Cellular Modem allows remote attackers to execute code through a malformed 5G Registration Accept message. The modem mishandles Rejected NSSAI information and writes it without enforcing the destination buffer's bounds. Exploitation requires cellular-network access but needs no device privileges or user interaction, with execution occurring in the modem context.
