Adjacent code execution via Wi-Fi P2P heap overflow
Published Sep 8, 2026 · Updated Sep 10, 2026
Heap buffer overflow in Google Android 16, 16 QPR2, and 17 allows physically proximate attackers to execute code through Wi-Fi P2P. The p2p_process_prov_disc_bootstrap_req function in p2p_pd.c writes beyond a heap buffer while processing a provisioning-discovery bootstrap request. No privileges or user interaction are required, but the attacker must be within reach of the adjacent Wi-Fi P2P interface; successful exploitation executes code.
