CVE-2025-23310Public exploitNetwork attack vector

Remote code execution via chunk-amplified stack allocation

Published Aug 6, 2025 · Updated Aug 6, 2025

Stack-based buffer overflow in NVIDIA Triton Inference Server before 25.07 allows remote attackers to execute code via crafted HTTP requests. HTTP handlers multiply the evbuffer_peek segment count influenced by chunked transfer encoding into an alloca-sized evbuffer_iovec array on the stack. No privileges or user interaction are required; exploitation can also crash the service or expose or alter data.
