Lifecycle Timeline
5DescriptionCVE.org
A security vulnerability has been detected in sonos tract up to 0.23.4. This impacts the function Tensor::from_raw_dt_align of the file data/src/tensor.rs of the component ONNX Initializer Loader. Such manipulation leads to incorrect calculation of buffer size. The attack may be launched remotely. The exploit has been disclosed publicly and may be used. The name of the patch is 66b10bda8895f4bfaf8c205361f0125cdf51f99b. It is best practice to apply a patch to resolve this issue.
AnalysisAI
Incorrect buffer size validation in Sonos Tract's ONNX Initializer Loader allows a crafted ONNX model file to crash the inference process. The Tensor::from_raw_dt_align function in data/src/tensor.rs accepts a raw byte slice and declared tensor shape without confirming the slice length matches the expected size, causing a Rust panic in copy_from_slice when dimensions mismatch. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target application loads an ONNX model containing a tensor initializer whose raw byte content length does not equal the byte count implied by its declared dtype and shape. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 5.3 (AV:N/AC:L/AT:N/PR:N/UI:P/VA:L) correctly frames this as moderate severity with limited impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A threat actor crafts an ONNX model file in which a tensor initializer's raw data payload is deliberately shorter than the size implied by its declared dtype and shape - for example, supplying 12 bytes for a float32 tensor with shape [2,3] that requires 24 bytes. When a victim ML pipeline built on Sonos Tract 0.23.x loads this model (via an upload endpoint, an automated model-fetch workflow, or a configured model path pointing to attacker-controlled storage), the from_raw_dt_align function panics inside copy_from_slice, crashing the inference process or service. … |
| Remediation | Apply the upstream fix by updating to a release of Sonos Tract that incorporates commit 66b10bda8895f4bfaf8c205361f0125cdf51f99b, merged via PR #2413 (https://github.com/sonos/tract/pull/2413). … Detailed patch versions, workarounds, and compensating controls in full report. |
