Local information disclosure via unchecked P2P lengths
Published Mar 24, 2023 · Updated Feb 25, 2025
Out-of-bounds reads in Android 13's p2p_iface.cpp allow local users with System execution privileges to disclose memory contents. Multiple paths in p2p_iface.cpp use input lengths without first checking that buffers are large enough, permitting reads beyond their bounds. Exploitation requires System execution privileges, needs no user interaction, and exposes information without reported modification or service interruption.
