CVE-2026-11329: Use of Weak Hash in onnx onnx-mlir
CVE-2026-11329 is a low-severity vulnerability in onnx-mlir version 0. 5. 0 where the function generate_hash_key uses a weak hash algorithm. This issue affects the Placeholder Node Cache Handler component and requires local access with high attack complexity to exploit. No known exploits are reported in the wild. A patch identified by commit 72c5187ff6d13c2c2b3d3789b8f5faf99f08a5b4 is available to address the weakness.
AI Analysis
Technical Summary
The vulnerability in onnx-mlir up to version 0.5.0 involves the use of a weak hash function in the generate_hash_key function within src/Runtime/python/torch_onnxmlir/src/torch_onnxmlir/backend.py. This weak hashing could potentially undermine the integrity of the Placeholder Node Cache Handler. Exploitation requires local access and is considered difficult due to high complexity. The issue has a CVSS 4.0 base score of 2.0, reflecting low severity. A patch commit (72c5187ff6d13c2c2b3d3789b8f5faf99f08a5b4) has been identified to fix the problem.
Potential Impact
The impact is limited due to the requirement for local access and high attack complexity. The weak hash usage could potentially allow manipulation or collision attacks within the Placeholder Node Cache Handler, but no known exploits exist. The low CVSS score indicates minimal risk under typical conditions.
Mitigation Recommendations
A patch identified by commit 72c5187ff6d13c2c2b3d3789b8f5faf99f08a5b4 is available and should be applied to remediate this vulnerability. Since the vendor advisory or official remediation level is not explicitly provided, users should verify and apply this patch from the onnx-mlir project repository. No additional mitigation steps are indicated.
