CVE-2026-84058

Estado: AnalizadaCrítica (9.8)—

IBM Guardium Data Protection 12.0, 12.1 y 12.2 es vulnerable a un desbordamiento de búfer en el decodificador de paquetes PRELOGIN de TDS (Microsoft SQL Server). Un atacante remoto que pueda enviar un paquete TDS PRELOGIN especialmente manipulado a una red supervisada por un IBM Guardium Collector puede provocar una denegación de servicio o, potencialmente, ejecutar código arbitrario en el dispositivo Collector.
