CVE-2026-47477Network attack vector

Unauthenticated service interruption via stack buffer overflow

Published Jul 14, 2026 · Updated Jul 14, 2026

Stack-based buffer overflow in NVIDIA Triton Inference Server 26.04 and earlier allows remote attackers to interrupt the Linux service. NVIDIA has not published the affected component, input field, or stack-copy operation that overruns the buffer. Unauthenticated network access is sufficient, and the reported consequence is limited to denial of service with no confidentiality or integrity impact.
