CVE-2018-9518

Estado: ModificadaAlta (7.8)—

En nfc_llcp_build_sdreq_tlv de llcp_commands.c, hay una posible escritura fuera de límites debido a la falta de una comprobación de límites. Esto podría llevar a un escalado de privilegios local, necesitando privilegios de ejecución System. No se necesita interacción del usuario para explotarlo. Producto: Android. Versiones: Android kernel. Android ID: A-73083945.
