CVE-2025-23335 (opens in a new tab)How to fix?
Upgrade triton-inference-server/server to version 2.58.0 or higher.
Overview
Affected versions of this package are vulnerable to Integer Underflow (Wrap or Wraparound) via the ShapeTensor::SetDataFromBuffer in the Tensor RT backend. An attacker could cause a denial of service by providing a specific model configuration and a specially crafted input.
Note: This vulnerability is only exploitable when using the default bundled Tensor RT backend /pytriton/tritonserver/backends/tensorry/libtriton_tensorrt.so.
Workaround
It is possible to update the Tensor RT backend to a patched version independently of the Triton Server; See Triton Inference Server Backend.
