CVE-2022-41901Public exploitNetwork attack vector

Process crash via non-scalar SparseMatrixNNZ input

Published Nov 18, 2022 · Updated Apr 22, 2025

Improper input validation in TensorFlow allows attackers to crash a process by passing a non-scalar tensor to SparseMatrixNNZ. ExtractVariantFromInput treats the sparse_matrix input as a scalar Variant without first verifying that its tensor shape has rank zero, which reaches a fatal CHECK. The crash occurs only when a consuming application invokes the affected raw operation with attacker-controlled input, and the demonstrated consequence is process interruption.
