Descriptions

The tcf_fill_node function in net/sched/cls_api.c in the netlink subsystem in the Linux kernel 2.6.x before 2.6.32-rc5, and 2.4.37.6 and earlier, does not initialize a certain tcm__pad2 structure member, which might allow local users to obtain sensitive information from kernel memory via unspecified vectors. NOTE: this issue exists because of an incomplete fix for CVE-2005-4881.

La función tcf_fill_node en net/sched/cls_api.c del subsistema netlink en el kernel de Linux v2.6.x hasta la v2.6.32-rc5, y v2.4.37.6 y anteriores, no inicializa un determinado miembro de la estructura tcm__pad2, lo que puede permitir a usuarios locales obtener información confidencial de la memoria del kernel a través de vectores de ataque sin especificar. NOTA: esta vulnerabilidad existe debido a una solución incompleta de CVE-2005-4881.
