Description
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to improper input validation in tf.raw_ops.SparseMatrixSparseCholesky when processing an invalid permutation argument. A local user can provide a specially crafted permutation input to cause a denial of service.
The issue can be triggered by a null pointer dereference after validation fails inside ValidateInputs but execution continues in the caller.
