CVE-2025-36906

Local privilege escalation via reduction heap overflow

Published Sep 4, 2025 · Updated Sep 4, 2025

Heap buffer overflow in Android's NeuralNetworks component allows local users to gain elevated privileges through a reduction operation. ConvertReductionOp in darwinn_mlir_converter_aidl.cc writes beyond a heap allocation while converting the reduction operation. Low-privileged local access is required; exploitation needs no user interaction and grants elevated privileges.
