Title
mm: fix NULL pointer dereference in alloc_pages_bulk_noprof
Summary
In the Linux kernel, the following vulnerability has been resolved: mm: fix NULL pointer dereference in alloc_pages_bulk_noprof We triggered a NULL pointer dereference for ac.preferred_zoneref->zone in alloc_pages_bulk_noprof() when the task is migrated between cpusets. When cpuset is enabled, in prepare_alloc_pages(), ac->nodemask may be &current->mems_allowed. when first_zones_zonelist() is called to find preferred_zoneref, the ac->nodemask may be modified concurrently if the task is migrated between different cpusets. Assuming we have 2 NUMA Node, when traversing Node1 in ac->zonelist, the nodemask is 2, and when traversing Node2 in ac->zonelist, the nodemask is 1. As a result, the ac->preferred_zoneref points to NULL zone. In alloc_pages_bulk_noprof(), for_each_zone_zonelist_nodemask() finds a allowable zone and calls zonelist_node_idx(ac.preferred_zoneref), leading to NULL pointer dereference. __alloc_pages_noprof() fixes this issue by checking NULL pointer in commit ea57485af8f4 ("mm, page_alloc: fix check for NULL preferred_zone") and commit df76cee6bbeb ("mm, page_alloc: remove redundant checks from alloc fastpath"). To fix it, check NULL pointer for preferred_zoneref->zone.

          "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mm: corregir la desreferencia de puntero NULL en alloc_pages_bulk_noprof Activamos una desreferencia de puntero NULL para ac.preferred_zoneref-\u0026gt;zone en alloc_pages_bulk_noprof() cuando la tarea se migra entre conjuntos de CPU. Cuando se habilita el conjunto de CPU, en prepare_alloc_pages(), ac-\u0026gt;nodemask puede ser \u0026amp;current-\u0026gt;mems_allowed. Cuando se llama a first_zones_zonelist() para encontrar preference_zoneref, ac-\u0026gt;nodemask puede modificarse simult\u00e1neamente si la tarea se migra entre diferentes conjuntos de CPU. Suponiendo que tenemos 2 nodos NUMA, al recorrer el nodo 1 en ac-\u0026gt;zonelist, la m\u00e1scara de nodo es 2, y al recorrer el nodo 2 en ac-\u0026gt;zonelist, la m\u00e1scara de nodo es 1. Como resultado, ac-\u0026gt;preferred_zoneref apunta a la zona NULL. En alloc_pages_bulk_noprof(), for_each_zone_zonelist_nodemask() encuentra una zona permitida y llama a zonelist_node_idx(ac.preferred_zoneref), lo que genera una desreferencia del puntero NULL. __alloc_pages_noprof() corrige este problema al verificar el puntero NULL en el commit ea57485af8f4 (\"mm, page_alloc: corregir la verificaci\u00f3n para la zona preferida NULL\") y el commit df76cee6bbeb (\"mm, page_alloc: eliminar las verificaciones redundantes de la ruta r\u00e1pida de asignaci\u00f3n\"). Para solucionarlo, verifique el puntero NULL para la zona preferida-\u0026gt;zone."

            "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mm: corregir la desreferencia de puntero NULL en alloc_pages_bulk_noprof Activamos una desreferencia de puntero NULL para ac.preferred_zoneref-\u0026gt;zone en alloc_pages_bulk_noprof() cuando la tarea se migra entre conjuntos de CPU. Cuando se habilita el conjunto de CPU, en prepare_alloc_pages(), ac-\u0026gt;nodemask puede ser \u0026amp;current-\u0026gt;mems_allowed. Cuando se llama a first_zones_zonelist() para encontrar preference_zoneref, ac-\u0026gt;nodemask puede modificarse simult\u00e1neamente si la tarea se migra entre diferentes conjuntos de CPU. Suponiendo que tenemos 2 nodos NUMA, al recorrer el nodo 1 en ac-\u0026gt;zonelist, la m\u00e1scara de nodo es 2, y al recorrer el nodo 2 en ac-\u0026gt;zonelist, la m\u00e1scara de nodo es 1. Como resultado, ac-\u0026gt;preferred_zoneref apunta a la zona NULL. En alloc_pages_bulk_noprof(), for_each_zone_zonelist_nodemask() encuentra una zona permitida y llama a zonelist_node_idx(ac.preferred_zoneref), lo que genera una desreferencia del puntero NULL. __alloc_pages_noprof() corrige este problema al verificar el puntero NULL en el commit ea57485af8f4 (\"mm, page_alloc: corregir la verificaci\u00f3n para la zona preferida NULL\") y el commit df76cee6bbeb (\"mm, page_alloc: eliminar las verificaciones redundantes de la ruta r\u00e1pida de asignaci\u00f3n\"). Para solucionarlo, verifique el puntero NULL para la zona preferida-\u0026gt;zone."
