CVE-2026-11329: Use of Weak Hash in onnx onnx-mlir
A vulnerability has been found in onnx onnx-mlir up to 0.5.0.0. Affected by this issue is the function generate_hash_key of the file src/Runtime/python/torch_onnxmlir/src/torch_onnxmlir/backend.py of the component Placeholder Node Cache Handler. Such manipulation leads to use of weak hash. An attack has to be approached locally. A high complexity level is associated with this attack. The exploitation is known to be difficult. The name of the patch is 72c5187ff6d13c2c2b3d3789b8f5faf99f08a5b4. Applying a patch is advised to resolve this issue.
AI Analysis
Technical Summary
The vulnerability CVE-2026-11329 in onnx-mlir up to version 0.5.0 involves the use of a weak hash function in the generate_hash_key function within the Placeholder Node Cache Handler component (file src/Runtime/python/torch_onnxmlir/src/torch_onnxmlir/backend.py). This weak hash usage could potentially undermine security properties relying on this hash. The attack requires local access and has a high complexity, making exploitation difficult. A patch commit 72c5187ff6d13c2c2b3d3789b8f5faf99f08a5b4 is advised to remediate the issue.
Potential Impact
The impact is limited due to the requirement for local access and high attack complexity. The weak hash usage may reduce the effectiveness of caching or integrity checks relying on the hash, but no direct remote exploitation or privilege escalation is indicated. The CVSS score of 2 reflects a low severity with limited impact and difficult exploitation.
Mitigation Recommendations
A patch identified by commit 72c5187ff6d13c2c2b3d3789b8f5faf99f08a5b4 is available and applying this patch is advised to resolve the weak hash usage vulnerability. No other mitigation or vendor advisory is provided, so users should update to a fixed version when available or apply the patch manually.
