CVE-2023-21007

Local information disclosure via unchecked address lengths

Published Mar 24, 2023 · Updated Feb 26, 2025

Out-of-bounds reads in Android 13's p2p_iface.cpp allow local users with System privileges to disclose process memory without interaction. Several P2P AIDL methods forward caller-supplied address buffers to core supplicant code without verifying the required MAC-address length. Exploitation requires local System-level execution; it exposes adjacent memory but provides no reported write, code-execution, or service-interruption capability.
