CVE-2024-53113 is a race-condition-driven NULL pointer dereference in the Linux kernel memory-management bulk page-allocation path, specifically alloc_pages_bulk_noprof(). With cpusets enabled, prepare_alloc_pages() can set the allocation context nodemask to the calling task's current memory-node allowance. If the task is concurrently migrated between cpusets while first_zones_zonelist() traverses the zonelist, that nodemask can change during traversal. This can leave ac.preferred_zoneref referring to an entry with a NULL zone. A subsequent allowable-zone lookup invokes zonelist_node_idx() using that invalid preferred zoneref and dereferences the NULL zone pointer. The upstream correction validates preferred_zoneref->zone before it is used, bringing the bulk allocation path in line with existing NULL handling in __alloc_pages_noprof().
