The issue arises when `mlir::tfg::ConvertGenericFunctionToFunctionDef` is given empty function attributes, resulting in a null dereference. Additionally, the `Eig` function can be fed an incorrect `Tout` input, leading to a `CHECK` fail that can trigger a denial of service attack. The `Eig` function is vulnerable when given specific inputs, such as `arg 0` with a shape of (2, 2) and `arg 1` set to `tf.complex128`. There are no known workarounds for this issue.
