picoquic before 2026.11.05.3e2e3d3 contains an integer overflow vulnerability in picoquic_decode_time_stamp_frame() that allows remote QUIC peers to corrupt stored timestamps by sending oversized TIME_STAMP values. Attackers on connections negotiating the TIME_STAMP extension can send large values shifted by ack_delay_exponent to wrap the result, corrupting RTT and bandwidth estimation and degrading congestion control.
