En la implementaci\u00f3n del protocolo SCTP ofrecida en el n\u00facleo de Linux, se ha detectado una vulnerabilidad (CVE-2026-64564) que permite a un usuario local obtener privilegios de root en el sistema. Entre otras cosas, esta vulnerabilidad permite acceder a root en el sistema principal al ejecutar un exploit en un contenedor aislado. Se ha preparado un prototipo de exploit, cuya funcionalidad ha sido demostrada en las distribuciones Debian 13, Rocky Linux 9, RHEL 9 y Ubuntu 24.04 con n\u00facleos 5.14, 6.6, 6.8 y 6.12. <\/p>\n

La vulnerabilidad se debe a la referencia a memoria ya liberada en el c\u00f3digo de reconfiguraci\u00f3n din\u00e1mica de direcciones SCTP (ASCONF). El n\u00facleo almacena en cach\u00e9 un puntero al transporte (asconf->transport) especificado en el paquete, pero la memoria asociada a ese puntero puede ser liberada, mientras que el puntero a la memoria ya liberada continuar\u00e1 utiliz\u00e1ndose para procesar otros comandos. El ataque se lleva a cabo enviando a un socket local una secuencia espec\u00edfica de comandos ASCONF de reconfiguraci\u00f3n de direcci\u00f3n: primero se env\u00eda un paquete DEL-IP para eliminar el transporte de una IP espec\u00edfica, seguido de un paquete DEL-IP con una m\u00e1scara de 0.0.0.0, cuyo procesamiento resultar\u00e1 en la reutilizaci\u00f3n del puntero colgante restante. <\/p>\n

La vulnerabilidad se debe a un error cometido hace 18 a\u00f1os en el n\u00facleo 2.6.25 (a\u00f1o 2008) y corregido en las versiones 6.6.148, 6.12.101, 6.18.42, 7.1.6 y 7.2-rc5. El estado de la correcci\u00f3n de vulnerabilidades en las distribuciones se puede evaluar en estas p\u00e1ginas: Debian, Ubuntu, SUSE\/openSUSE, RHEL, Gentoo, Arch, Fedora.
