Local memory disclosure via unchecked buffer lengths
Published Mar 24, 2023 · Updated Feb 26, 2025
Out-of-bounds reads in Android 13 p2p_iface.cpp allow local users with System privileges to disclose process memory without user interaction. Affected Wi-Fi P2P AIDL methods pass unchecked MAC-address or WPS device-type buffers into core supplicant code, which reads beyond their bounds. Exploitation requires System execution privileges on the device; it exposes memory but does not grant code execution, modify data, or interrupt service.
