Miggo AIRoot Cause Analysis

The vulnerability stems from two specific CHECK assertions in IsSimplifiableReshape:

  1. CHECK_LE(2, node.input_size()) - Could fail if Reshape node has <2 inputs
  2. CHECK_EQ(1, outputs.size()) - Could fail if shape evaluation produced ≠1 output These were replaced with error returns in the patches (1fb2773 and 2406555). The CWE-617 (Reachable Assertion) classification confirms this pattern. The function's role in processing Reshape operations during optimization makes it a clear attack surface for crafted models.
