CVE-2024-56189Network attack vector

Remote information disclosure via unchecked modem message bounds

Published Sep 4, 2025 · Updated Sep 8, 2025

Out-of-bounds read in the Pixel modem component of Google Cloud Android kernel allows remote authenticated users to disclose memory. SAEMM_DiscloseMsId in SAEMM_RadioMessageCodec.c reads beyond the intended buffer because it processes radio-message data without a required bounds check. Exploitation requires post-authentication network access, needs no user interaction, and exposes memory without reported integrity or availability impact.
